16-BIT CMOS MICROCOMPUTER
DESCRIPTION
These are single-chip 16-bit microcomputers designed with high-per-formance CMOS silicon gate technology, including the internal flashmemory and being packaged in 42-pin plastic molded SSOP orshrink plastic molded DIP. These microcomputers support the 7900Series instruction set, which are enhanced and expanded instructionset and are upper-compatible with the 7700/7751 Series instructionset.
The CPU of these microcomputers is a 16-bit parallel processor thatcan also be switched to perform 8-bit parallel processing. Also, thebus interface unit of these microcomputers enhances the memoryaccess efficiency to execute instructions fast. Therefore, these mi-crocomputers are suitable for office, business, and industrial equip-ment controller that require high-speed processing of large data.Also, they are suitable for motor-control equipment since each ofthem includes the motor control circuit.
For the internal flash memory, single-power-supply programmingand erasure, using a PROM programmer or the control by the cen-tral processing unit (CPU), is supported. Also, each of these micro-computers has the memory area dedicated for storing a certainsoftware which controls programming and erasure (reprogrammingcontrol software). Therefore, on these microcomputers, the programcan easily be changed even after they are mounted on the board.

This parallel program-mer uses the software commands listed in Table 1 to do the flashmemory manipulations, such as read/programming/erase opera-tions. User ROM Area and Boot ROM Area The user ROM area and boot ROM area can be reprogrammed inthe flash memory parallel I/O mode. The programming and block erase operations can be performed onlyto these areas. The boot ROM area, 8 Kbytes in size, is assigned to addresses000016–1FFF16, so that programming and block erase operationscan be performed only to this area. (Access to any address out ofthis area is prohibited). The erasable block in the boot ROM area is only one block, consist-ing of 8 Kbytes. The reprogramming control firmware to be used inthe flash memory serial I/O mode has been stored to this boot ROMarea on our shipment. Therefore, do not reprogram the boot ROMarea if the user uses the flash memory serial I/O mode. Do not program to addresses FF9016 to FF9F16 because this area isthe reserved area for the programmer. Note that, when the boot ROM area is read out from the CPU in theCPU reprogramming mode, described later, its addresses will beshifted to E00016—FFFF16. Table 1.

In this mode, being different from the flash memory parallel I/Omode, the CPU controls reprogramming of the flash memory (usingthe CPU reprogramming mode), serial input of the reprogrammingdata, etc. The reprogramming control firmware for the flash memory serial I/Omode has been stored in the boot ROM area on shipment of theproduct from us. Note that, then, the flash memory serial I/O modewill become unavailable if the boot ROM area has been repro-grammed in the flash memory parallel I/O mode. Note that, also, this reprogramming control firmware for the flashmemory serial I/O mode is subject to change. Figures 5 and 6 show the pin connections in the flash memory serialI/O mode. The three pins, SCLK, SDA, and BUSY, are used to input and outputserial data. The SCLK pin is the input pin of external transfer clocks. The SDApin is the I/O pin of transmit and receive data, and its output acts asthe N-channel open-drain output. To the SDA pin, connect an exter-nal pullup resistor (about 1 kΩ). The BUSY pin is the output pin of theBUSY flag (CMOS output) and goes “H” during BUSY periods owingto a certain operation, such as transmit, receive, erase, program-ming, etc. Transmit and receive data are serially transferred 8 bits at a time.In the flash memory serial I/O mode, only the user ROM area can bereprogrammed; the boot ROM area is not accessible. Addresses FF9016 to FF9F16 are the reserved area for the serialprogrammer.

In this mode, only the user ROM area can be reprogrammed; theboot ROM area cannot be reprogrammed. The user-original reprogramming control software for the CPU repro-gramming mode can be stored in either the user ROM area or theboot ROM area. Because the CPU cannot read out the flash memory in the CPU re-programming mode, the above software must be transferred to theinternal RAM in advance to be executed. Boot Mode The user-original reprogramming control software for the CPU repro-gramming mode must be stored into the user ROM area or the bootROM area in the flash memory parallel I/O mode in advance. (If thisprogram has been stored into the boot ROM area, the flash memoryserial I/O mode will become unavailable). Note that addresses of the boot ROM area depend on the accessingways to the boot ROM area, When accessing in the flash memoryparallel I/O mode, these addresses will be shifted to 000016 to1FFF16. On the other hand, when accessing with the CPU, these ad-dresses will be shifted to E00016 to FFFF16. Reset removal with both of the MD0 and MD1 pins held “L” invokesthe normal microcomputer mode, and the CPU operates using thecontrol software stored in the user ROM area. In this case, the bootROM area is not accessible. Removing reset with the MD0 pin held “L” and the MD1 pin “H”, theCPU starts its operation using the reprogramming control softwarestored in the boot ROM area. This mode is called the boot mode. Thereprogramming control software in the boot ROM area can also re-program the user ROM area.

In the CPU reprogramming mode, the CPU erases, programs, andreads the internal flash memory by writing software commands. Notethat the user-original reprogramming control software must be trans-ferred to the internal RAM in advance to be executed. The CPU reprogramming mode becomes active when “1” is writteninto the flash memory control register’s bit 1 (the CPU reprogram-ming mode select bit) shown in Figure 7, and software commandsbecome acceptable. In the CPU reprogramming mode, software commands and data areall written to and read from even addresses (Note that address A0 inbyte addresses = “0”.) 16 bits at a time. Therefore, a software com-mand consisting of 8 bits must be written to an even address; there-fore, any command written to an odd address will be invalid. Sincethe write data at the 2nd cycle of a programming command consistsof 16 bits, this data must be written to even and odd addresses.The seaquencer in the flash memory controls the erase and pro-gramming operations. What the status of the seaquencer operationis and whether the programming or erase operation has been com-pleted normally or terminated by an error can be examined by read-ing the flash memory control register. Figure 7 shows the bit configuration of the flash memory control reg-ister. Bit 0 (the RY/BY status bit) is a read-only bit for indicating the sea-quencer operation. This bit goes to “0” (BUSY) while the automaticprogramming/erase operation is active and goes to “1” (READY) dur-ing the other operations. Bit 1 serves as the CPU reprogramming mode select bit. Writing of“1” to this bit selects the CPU reprogramming mode, and softwarecommands will be acceptable. Because the CPU cannot directly ac-cess the internal flash memory in the CPU reprogramming mode,writing to this bit 1 must be performed by the user-original repro-gramming control software which has been transferred to the inter-nal RAM in advance. To set bit 1 to “1”, it is necessary to write “0” and“1” to this bit 1 successively. On the other hand, to clear this bit to “0”,it is sufficient only to write “0”. Bit 3 (the flash memory reset bit) resets the control circuit of the in-ternal flash memory and is used when the CPU reprogrammingmode is terminated or when an abnormal access to the flashmemory happens. Writing of “1” to bit 3 with the CPU reprogrammingmode select bit = “1” preforms the reset operation. To remove thereset, write “0” to bit 3 after confirming bit 0 (the RY/BY status bit) be-comes “1”. Bit 5 serves as the user ROM area select bit and is valid only in theboot mode. Setting this bit to “1” in the boot mode switches an acces-sible area from the boot ROM area to the user ROM area. To use theCPU reprogramming mode in the boot mode, set this bit to “1”. Notethat when the microcomputer is booted up in the user ROM area,only the user ROM area is accessible and bit 5 is invalid; on the otherhand, when the microcomputer is in the boot mode, bit 5 is valid in-dependent of the CPU reprogramming mode. To rewrite bit 5, ex-ecute the user-original reprogramming control software transferredto the internal RAM in advance. Figure 8 shows the CPU reprogramming mode set/termination flow- chart, and be sure to follow this flowchart. As shown in Note 1 of Fig-ure 8, before selecting the CPU reprogramming mode, set “0” to theprocessor mode register 1’s bit 7 (the internal ROM bus cycle selectbit) and set flag I to “1” to avoid an interrupt request input. When a watchdog timer interrupt request is generated in the CPUreprogramming mode, when an input to the RESET pin is “L”, orwhen the software reset is performed, the flash memory control cir-cuit and flash memory control register will be reset. When the flash memory is reset during the erase or programmingoperation, this operation is cancelled and the target block’s data willbe invalid. Just before writing a software command related to theerase/programming operation, be sure to write to the watchdogtimer. In the CPU reprogramming mode, be sure not to use the STPand WIT instructions. 18 元器件交易网www.cecb2b.com ILEPRge.ion.icatto chanfice l spject finare suba to a is nimitsThisetric l :emicNote paramoSMYRAINMITSUBISHI MICROCOMPUTERS M37906F8CFP, M37906F8CSP 16-BIT CMOS MICROCOMPUTER Software Commands StartSingle-chip mode,Memory expansion mode,or Boot modeTable 2 lists the software commands. By writing a software command after the CPU reprogramming modeselect bit has been set to “1”, erasing, programming, etc. can bespecified. Note that, at software commands’ input, the high-orderbyte (D8–D15) is ignored. (Except for the write data at the 2nd cycleof a programming command.) Software commands are explained as below. The processor mode register 1 is set (Note 1).Flag I is set to “1”.Read Array Command (FF16) By writing command code “FF16” at the 1st bus cycle, the microcom-puter enters the read array mode. If an address to be read is input inthe next or the following bus cycles, the contents at the specified ad-dress are output to the data bus (D0 to D15) in a unit of 16 bits. The read array mode is maintained until writing of another softwarecommand. The user-original reprogramming control software for the CPU reprogramming mode is transferred to the internal RAM.Jump to the above software in the internal RAM.(The operations shown below will be executed by the above software in this RAM.)Read Status Register Command (7016) Writing command code “7016” at the 1st bus cycle outputs the con-tents of the status register to the data bus (D0-D7) by a read at the2nd bus cycle. The status register is explained later. (Only in the boot mode.)The user ROM area select bit is set to “1”.Clear Status Register Command (5016) Writing of “1” to the CPU reprogramming mode select bit.(Writing of “0” → Writing of “1”)This command clears two status bits (SR.4, 5) each of which is setto “1” to indicate that the operation has been terminated by an error.To clear these bits, write command code “5016” at the 1st bus cycle. Operations such as erasing, programming are executed by using software commands.Programming Command (4016) This command facilitates programming of 1 word (2 bytes) at a time.To initiate programming, write command code “4016” at the 1st buscycle; when write data is written in a unit of 16 bits at the 2nd buscycle, the address is specified at the same time. Upon completion ofdata writing, automatic programming (data programming and verifi-cation) operation is started. The completion of the automatic programming operation is con-firmed by a read of the flash memory control register. The RY/BY sta-tus bit of the flash memory control register goes “0” during theautomatic programming operation; and also, it goes “1” after the endof it. Before execution of the next command, be sure to confirm that theRY/BY status bit is set to “1” (READY). During the automatic pro-gramming operation, writing of commands and access to the flashmemory must not be performed. When programming continuously, the programming command canbe executed with the read status register mode kept if there is noprogramming error. Simultaneously with start of the automatic pro-gramming, the read status register mode is automatically active. Inthis case, the read status register mode is retained until the next readarray command (FF16) is written or until the reset is performed byusing the flash memory reset bit. Reading out the status register after the automatic programming op-eration is completed reports the result of it. For details, refer to thesection on the status register. Figure 9 shows an example of the programming flowchart. Additional programming to any word that has already been pro-grammed is prohibited.

Before execution of these commands, execute the clearstatus register command (5016), in advance, to clear these statusbits. Both of SR.4, SR.5 are set to “1” under the following conditions(Command Sequence Error): Full Status Check The full status check reports the results of the erase or programmingoperation. Figure 11 shows the full status check flowchart and actions to betaken if an error has occurred. Table 3.
