(1) MCU mode In the MCU mode, the TMP86F808 is a pin compatible with the TMP86C408/808 (Make sure to fix the TEST pin to low level). (2) Serial PROM mode The serial PROM mode is set by fixing TEST pin, P10 and P11 at "high" respectively when RESET pin is fixed "low". After release of reset, the built-in BOOT ROM program is activated and the built-in flash memory is rewritten by serial I/F (UART).

The TMP86F808 has flash memory in place of the mask ROM which is included in the TMP86C408/808. The configuration and function are the same as the TMP86C408/808. 1. Operating Mode The TMP86F808 has MCU mode and serial PROM mode. 1.1 MCU Mode The MCU mode is set by fixing the TEST pin to the low level. In the MCU mode, the operation is the same as the TMP86C408/808. 1.1.1 Program memory The TMP86F808 has a 8-Kbyte built-in flash memory (addresses E000H to FFFFH in the MCU mode). When using TMP86F808 for evaluation of TMP86C408/808, the program is written by the serial PROM mode. 0000H 0000H E000H Program FFFFH TMP86C808 E000H Program FFFFH MCU mode TMP86F808 (a) ROM Size = 8 Kbytes 0000H 0000H F000H Program FFFFH TMP86C408 F000H Program FFFFH MCU mode TMP86F808 (b) ROM Size = 4 Kbytes Figure 1.1.1 Program Memory Area Note: The area that is not in use should be set data to FFH. 86F808-6 2007-08-07 TMP86F808 1.1.2 1.1.3 Data Memory TMP86F808 has a built-in 256-byte data memory (Static RAM).

(2) I/O ports The I/O circuitries of TMP86F808 I/O ports are the same as the those of TMP86C408/808. 86F808-7 2007-08-07 TMP86F808 2. Serial PROM Mode 2.1 Outline The TMP86F808 has a 2-Kbyte BOOT ROM for programming to flash memory. This BOOT ROM is a mask ROM that contains a program to write the flash memory on-board. The BOOT ROM is available in a serial PROM mode and it is controlled by TEST pin and RESET pin and 2 I/O pins, and is communicated with UART. There are four operation modes in a serial PROM mode: flash memory writing mode, RAM loader mode, flash memory SUM output mode and product discrimination code output mode. Operating area of serial PROM mode differs from that of MCU mode. The operating area of serial PROM mode shows in Table 2.1.1.

Before on-board programming can be executed, the communication format on the external controller side must also be setup in the same way as for this product. Note that although the default baud rate is 9,600 bps, it can be changed to other values as shown in Table 2.4.1. The Table 2.4.2 shows an operating frequency and baud rate in serial PROM mode. Except frequency which is not described in Table 2.4.2 can not use in serial PROM mode. Baud rate (Default): 9,600 bps Data length: 8 bits Parity addition: None Stop bit length: 1 bit Table 2.4.1 Baud Rate Modification Data Baud rate modification data Baud rate (bps) 04H 76800 05H 62500 07H 38400 0AH 31250 18H 19200 28H 9600 Table 2.4.2 Operating Frequency and Baud Rate in Serial PROM Mode Reference Baud 76800 Rate (Baud) Baud Rate 04H Modification Data Reference Frequency (bps) (%) (MHz) 2 4 8 16 - - - 76923 - - - +0.16 62500 05H (bps) - - 62500 62500 38400 07H (bps) - - 38462 38462 31250 0AH (bps) - 31250 31250 31250 19200 18H (bps) - 19231 19231 19231 9600 28H (bps) 9615 9615 9615 9615 (%) - - 0.00 0.00 (%) - - +0.16 +0.16 (%) - 0.00 0.00 0.00 (%) - +0.16 +0.16 +0.16 (%) +0.16 +0.16 +0.16 +0.16 Note: "Reference Frequency" shows the high-frequency area supported in serial PROM mode. Except the above frequency can not be supported in serial PROM mode. 2.5 Command There are five commands in serial PROM mode. After reset release, the TMP86F808 waits a matching data (5AH). Table 2.5.1 Command in Serial PROM Mode Command Data 5AH 30H 60H 90H C0H Operation Mode Setup Flash memory writing RAM loader Flash memory SUM output Product discrimination code output Remarks Matching data. Always start with this command after reset release. Writing to area from E000H to FFFFH is enable. Writing to area from 0050H to 0130H is enable. The checksum of entire flash memory area (from E000H to FFFFH) is output in order of the upper byte and the lower byte. Product discrimination code, that is expressed by 13 bytes data, is output. 86F808-11 2007-08-07 TMP86F808 2.6 Operation Mode There are four operating modes in serial PROM mode: Flash memory writing mode, RAM loader mode, flash memory SUM output mode and product discrimination code output mode. For details about these modes, refer to (1) Flash memory writing mode through (4) Product discrimination code output mode. (1) Flash memory writing mode The data are written to the specified flash memory addresses. The controller should send the write data in the Intel Hex format (Binary). For details of writing data format, refer to 2.7 "Flash Memory Writing Data Format". If no errors are encountered till the end record, the SUM of 8 Kbytes of flash memory is calculated and the result is returned to the controller. To execute the flash memory writing mode, the TMP86F808 checks the passwords except a blank product. If the passwords did not match, the program is not executed. (2) RAM loader mode The RAM loader transfers the data into the internal RAM that has been sent from the controller in Intel Hex format. When the transfer has terminated normally, the RAM loader calculates the SUM and sends the result to the controller before it starts executing the user program. After sending of SUM, the program jumps to the start address of RAM in which the first transferred data has been written. This RAM loader function provides the user's own way to control on-board programming. To execute the RAM loader mode, the TMP86F808 checks the passwords except a blank product. If the passwords did not match, the program is not executed. (3) Flash memory SUM output mode The SUM of 8 Kbytes of flash memory is calculated and the result is returned to the controller. The BOOT ROM does not support the reading function of the flash memory. Instead, it has this SUM command to use. By reading the SUM, it is possible to manage Revisions of application programs. (4) Product discrimination code output mode The product discrimination code is output as a 13-byte data, that includes the start address and the end address of ROM. (In case of TMP86F808, the start address is E000H and the end address is FFFFH.) Therefore, the controller can recognize the device information by using this function. 86F808-12 2007-08-07 TMP86F808 2.6.1 Flash Memory Writing Mode (Operation command: 30H) Table 2.6.1 shows flash memory writing mode process.

For details, refer to 2.8 "Error Code". Note 2: Refer to 2.10 "Intel Hex Format (Binary)". Note 3: Refer to 2.9 "Checksum (SUM)". Note 4: Refer to 2.11 "Passwords". Note 5: If all data of vector area are "00H" or "FFH", the passwords comparison is not executed because the device is considered as blank product. However, it is necessary to specify the password count storage addresses and the password comparison start address even though it is a blank product. If a password error occurs, the UART function of TMP86F808 stops without returning error code to the controller. Therefore, when a password error occurs, the TMP86F808 should be reset by RESET pin input. Note 6: The time between data records needs over 1 ms. 86F808-13 2007-08-07 TMP86F808 Description of flash memory writing mode 1. The receive data in the 1st byte is the matching data. When the boot program starts in serial PROM mode, TMP86F808 (Mentioned as "device" hereafter) waits for the matching data (5AH) to receive. Upon receiving the matching data, it automatically adjusts the UART's initial baud rate to 9,600bps. When the device has received the matching data, the device transmits the data "5AH" as an echo back to the controller. If the device can not receive the matching data, the device does not transmit the echo back data and waits for the matching data again with changing baud rate. Therefore, the controller should send the matching data continuously until the device transmits the echo back data. The receive data in the 3rd byte is the baud rate modification data. The six kinds of baud rate modification data shown in Table 2.4.1 are available. Even if baud rate changing is no need, be sure to send the initial baud rate data (28H: 9,600 bps). The changing of baud rate is executed after transmitting the echo back data. When the 3rd byte data is one of the baud rate modification data corresponding to the device's operating frequency, the device sends the echo back data which is the same as received baud rate modification data. Then the baud rate is changed. If the 3rd byte data does not correspond to the baud rate modification data, the device stops UART function after sending 3 bytes of baud rate modification error code: (62H). The receive data in the 5th byte is the command data (30H) to write the flash memory. When the 5th byte is one of the operation command data shown in Table 2.5.1, the device sends the echo back data which is the same as received operation command data (in this case, 30H). If the 5th byte data does not correspond to the operation command data, the device stops UART function after sending 3 bytes of operation command error code: (63H). The 7th byte is used as an upper bit (Bit15 to bit8) of the password count storage address. When the receiving is executed correctly (No error), the device does not send any data. If the receiving error or password error occur, the device does not send any data and stops UART function. The 9th byte is used as a lower bit (Bit7 to bit0) of the password count storage address. When the receiving is executed correctly (No error), the device does not send any data. If the receiving error or password error occur, the device does not send any data and stops UART function. The 11th byte is used as an upper bit (Bit15 to bit8) of the password comparison start address. When the receiving is executed correctly (No error), the device does not send any data. If the receiving error or password error occur, the device does not send any data and stops UART function. 2. 3. 4. 5. 6. 7. 8. 9. 10. The 13th byte is used as a lower bit (Bit7 to bit0) of the password comparison start address. When the receiving is executed correctly (No error), the device does not send any data. If the receiving error or password error occur, the device does not send any data and stops UART function. 11. The 15th through the m'th bytes are the password data. The number of passwords is the data (N) indicated by the password count storage address. The password data are compared for N entries beginning with the password comparison start address. The controller should send N bytes of password data to the device. If the passwords do not match, the device stops UART function without returning error code to the controller. If the data of vector addresses (FFE0H to FFFFH) are all "FFH", the comparison of passwords is not executed because the device is considered as a blank product. 86F808-14 2007-08-07 TMP86F808 12. The receive data in the m'th + 1 through n'th - 2 byte are received as binary data in Intel Hex format. No received data are echoed back to the controller. The data which is not the start mark (3AH for ":") in Intel Hex format is ignored and does not send an error code to the controller until the device receives the start mark. After receiving the start mark, the device receives the data record, that consists of length of data, address, record type, writing data and checksum. After receiving the checksum of data record, the device waits the start mark data (3AH) again. The data of data record is temporarily stored to RAM and then, is written to specified flash memory by page (32 bytes) writing. For details of an organization of flash memory, refer to 2. "Serial PROM Mode". Since after receiving an end record, the device starts to calculate the SUM, the controller should wait the SUM after sending the end record. If receive error or Intel Hex format error occurs, the device stops UART function without returning error code to the controller. 13. The n'th - 1 and the n'th bytes are the SUM value that is sent to the controller in order of the upper byte and the lower byte. For details on how to calculate the SUM, refer to 2.9 "Checksum (SUM)". The SUM calculation is performed after detecting the end record, but the calculation is not executed when receive error or Intel Hex format error has occurred. The time required to calculate the SUM of the 8 Kbytes of Flash memory area is approximately 100 ms at fc = 16 MHz. After the SUM calculation, the device sends the SUM data to the controller. After sending the end record, the controller can judge that the transmission has been terminated correctly by receiving the checksum. 14. After sending the SUM, the device waits for the next operation command data. 86F808-15 2007-08-07 TMP86F808 2.6.2 RAM Loader Mode (Operation command: 60H) Table 2.6.2 shows RAM loader mode process.

Note 1: "xxH x 3" denotes that operation stops after sending 3 bytes of xxH. For details, refer to 2.8 "Error Code". Note 2: Refer to 2.10 "Intel Hex Format (Binary)". Note 3: Refer to 2.9 "Checksum (SUM)". Note 4: Refer to 2.11 "Passwords". 86F808-16 2007-08-07 TMP86F808 Note 5: If all data of vector area are "00H" or "FFH", the passwords comparison is not executed because the device is considered as blank product. However, it is necessary to specify the password count storage addresses and the password comparison start address even though it is a blank product. If a password error occurs, the UART function of TMP86F808 stops without returning error code to the controller. Therefore, when a password error occurs, the TMP86F808 should be reset by RESET pin input. Note 6: Do not send only end record after transferring of password string. If the TMP86F808 receives the end record only after reception of password string, it does not operate correctly. Description of RAM loader mode 1. 2. 3. The process of the 1st byte through the 4th byte are the same as flash memory writing mode. The receive data in the 5th byte is the RAM loader command data (60H) to write the user's program to RAM. When the 5th byte is one of the operation command data shown in Table 2.5.1, the device sends the echo back data which is the same as received operation command data (in this case, 60H). If the 5th byte data does not correspond to the operation command data, the device stops UART function after sending 3 bytes of operation command error code: (63H). The process of the 7th byte through the m'th byte are the same as flash memory writing mode. The receive data in the m'th + 1 through n'th - 2byte are received as binary data in Intel Hex format. No received data are echoed back to the controller. The data which is not the start mark (3AH for ":") in Intel Hex format is ignored and does not send an error code to the controller until the device receives the start mark. After receiving the start mark, the device receives the data record, that consists of length of data, address, record type, writing data and checksum. After receiving the checksum of data record, the device waits the start mark data (3AH) again. The data of data record is written to specified RAM by the receiving data. Since after receiving an end record, the device starts to calculate the SUM, the controller should wait the SUM after sending the end record. If receive error or Intel Hex format error occurs, the UART function of TMP86F808 stops without returning error code to the controller. The n'th - 1 and the n'th bytes are the SUM value that is sent to the controller in order of the upper byte and the lower byte. For details on how to calculate the SUM, refer to 2.9 "Checksum (SUM)". The SUM calculation is performed after detecting the end record, but the calculation is not executed when receive error or Intel Hex format error has occurred. The SUM is calculated by the data written to RAM, but the length of data, address, record type and checksum in Intel Hex format are not included in SUM. The boot program jumps to the first address that is received as data in Intel Hex format after sending the SUM to the controller. 4. 5. 6. 7. 86F808-17 2007-08-07 TMP86F808 2.6.3 Flash Memory Memory SUM Output Mode (Operation command: 90H) Table 2.6.3 shows flash memory SUM output mode process.

For details, refer to 2.8 "Error Code". Note 2: Refer to 2.9 "Checksum (SUM)" Description of flash memory SUM output mode 1. 2. 3. The process of the 1st byte through the 4th byte are the same as flash memory writing mode. The receive data in the 5th byte is the flash memory SUM command data (90H) to calculate the entire flash memory. When the 5th byte is one of the operation command data shown in Table 2.5.1, the device sends the echo back data which is the same as received operation command data (in this case, 90H). If the 5th byte data does not correspond to the operation command data, the device stops UART function after sending 3 bytes of operation command error code: (63H). The 7th and the 8th bytes are the SUM value that is sent to the controller in order of the upper byte and the lower byte. For details on how to calculate the SUM, refer to 2.9 "Checksum (SUM)". After sending the SUM, the device waits for the next operation command data. 4. 5. 86F808-18 2007-08-07 TMP86F808 2.6.4 Product Discrimination Code Output Mode (Operation command: C0H) Table 2.6.4 shows product discrimination code output mode process.

For details, refer to 2.8 "Error Code". Description of product discrimination code output mode 1. 2. 3. The process of the 1st byte through the 4th byte are the same as flash memory writing mode. The receive data in the 5th byte is the product discrimination code output command data (C0H). When the 5th byte is one of the operation command data shown in Table 2.5.1, the device sends the echo back data which is the same as received operation command data (in this case, C0H). If the 5th byte data does not correspond to the operation command data, the device stops UART function after sending 3 bytes of operation command error code: (63H). The 9th and the 19th bytes are the product discrimination code. For details, refer to 2.12 "Product Discrimination Code". After sending the SUM, the device waits for the next operation command data. 4. 5. 86F808-19 2007-08-07 TMP86F808 2.7 Flash Memory Writing Data Format Flash memory area of TMP86F808 consists of 255 pages and one page size is 32 bytes. Writing to flash memory is executed by page writing. Therefore, it is necessary to send 32 bytes data (for one page) even though only a few bytes data are written. Figure 2.7.1 shows an organization of flash memory area. When the controller sends the writing data to the device, be sure to keep the format described below. 1. 2. The address of data after receiving the flash memory writing command should be the first address of page. For example, in case of page 2, the first address should be E040H. If the last data's address of data record is not end address of page, the address of the next data record should be the address + 1 and the last data's address must point to the last address of this page. For example, if the last data's address is E00FH (Page0), the address of the next data record should be E010H (Page0) and the address of the last data should be E01FH (Page0). The last data's address of data record immediately before sending the end record should be the last address of page. For example, in case of page 1, the last data's address of data record should be E03FH. Note: Do not write only the vector area (FFF0H to FFFFH) when all data of flash memory are the same data. If the vector area is only written, the next operation can not be executed because of password error. 2 3 4 3.

Table 2.8.1 Error Code Transmit Data 62H, 62H, 62H 63H, 63H, 63H A1H, A1H, A1H A3H, A3H, A3H Meaning of Transmit Data Baud rate modification error occurred. Operating command error occurred. Framing error in received data occurred. Overrun error in received data occurred. 2.9 Checksum (SUM) (1) Calculation method SUM consists of byte + byte.... + byte, the checksum of which is returned in word as the result. Namely, data is read out in byte and checksum of which is calculated, with the result returned in word. Example: A1H B2H C3H D4H If the data to be calculated consists of the four bytes shown to the left, SUM of the data is A1H + B2H + C3H + D4H = 02EAH = 02H SUM (HIGH) SUM (LOW) = EAH The SUM returned when executing the flash memory write command, RAM loader command, or flash memory SUM command is calculated in the manner shown above. (2) Calculation data The data from which SUM is calculated are listed in Table 2.9.1 below. Table 2.9.1 Checksum Calculation Data Operating Mode Calculation Data Remarks Even when written to part of the flash memory area, Flash memory writing mode data in the entire memory area (8 Kbytes) is Data in the entire area (8 Kbytes) of flash calculated. memory Flash memory Checksum output The length of data, address, record type and mode checksum in Intel Hex format are not included in SUM. The length of data, address, record type and RAM loader mode Data written to RAM checksum in Intel Hex format are not included in SUM. Product discrimination code out- Checksum of transferred data (from 9th to For details, refer to "2.6.4 Product Discrimination put mode 18th byte) Code Output Mode". 86F808-21 2007-08-07 TMP86F808 2.10 Intel Hex Format (Binary) 1. After receiving the SUM of a record, the device waits for the start mark data (3AH for ":") of the next record. Therefore, the device ignores the data, which does not match the start mark data after receiving the SUM of a record. Make sure that once the controller program has finished sending the SUM of the end record, it does not send anything and waits for two bytes of data to be received (Upper and lower bytes of SUM). This is because after receiving the SUM of the end record, the boot program calculates the SUM and returns the calculated SUM in two bytes to the controller. If a receive error or Intel Hex format error occurs, the UART function of TMP86F808 stops without returning error code to the controller. In the following cases, an Intel Hex format error occurs: * * * * * When the record type is not 00H, 01H, or 02H When a SUM error occurred When the data length of an extended record (Type = 02H) is not 02H When the address of an extended record (Type = 02H) is larger than 1000H and after that, receives the data record When the data length of the end record (Type = 01H) is not 00H 2. 3. 2.11 Passwords The area in which passwords can be specified is located at addresses E000H to FF9FH. The vector area (from FFA0H to FFFFH) can not be specified as passwords area. The device compares the stored passwords with the passwords, which are received from the controller. If all data of vector area are "00H" or "FFH", the passwords comparison is not executed because the device is considered as blank product. It is necessary to specify the password count storage addresses and the password comparison start address even though it is a blank product. Table 2.11.1 Password Setting in the Blank Product and Non Blank Product Password PNSA (Password count storage addresses) PCSA (Password comparison start address) N (Password count) Setting of password Blank Product(Note 1) E000H PNSA FF9FH E000H PCSA FF9FH * No need Non Blank Product E000H PNSA FF9FH E000H PCSA FFA0-N 8N Need (Note 2) Note 1: When all data of addresses from FFE0H to FFFFH area are "00H" or "FFH", the device is judged as blank product. Note 2: The same three or more bytes consecutive data can not be used as password. When the password includes the same consecutive data (three or more bytes), the password error occurs. If the password error occured, the UART function of device stops without returning error code. Note 3: *: Don't care. Note 4: When the password doesn't match the above condition, the password error occurs. If the password error occured, the UART function of device stops without returning error code. Note 5: In case of the blank product, the device receives Intel Hex Format immediately after receiving PCSA without receiving password strings. In this time, because the device ignores the data 86F808-22 2007-08-07 TMP86F808 except the start mark data (3AH for ":") as Intel Hex Format data, even if external controller transmitted dummy password strings, process operates correctly. However, if the dummy password strings contain data "3AH", the device detects it as start mark data mistakenly, and device stops process without returning error doce. Therefore, if these process becomes issue, the external controller should not transmit the dummy password strings.

Password string A password string sent from the controller is compared with the specified data in the flash memory. If the password string does not match the specified data in the flash memory, a password error occurs and the TMP86F808 stops operating. 4. Handling of password error If a password error occurs, the UART function of TMP86F808 stops without returning error code to the controller. Therefore, when a password error occurs, the TMP86F808 should be reset by RESET pin input. 2.12 Product Discrimination Code The product discrimination code is a 13-byte data, that includes the start address and the end address of ROM.
