19 / 32 page  86FS27-19 2007-08-07 TMP86FS27 2.6.4 Product Discrimination Code Output Mode (Operation command: C0H) Table 2.6.4 shows product discrimination code output mode process. Table 2.6.4 Product Discrimination Code Output Process Note: “xxH × 3” denotes that operation stops after sending 3 bytes of xxH. For details, refer to 2.8 “Error Code”. Description of product discrimination code output mode 1. The process of the 1st byte through the 4th byte are the same as flash memory writing mode. 2. The receive data in the 5th byte is the product discrimination code output command data (C0H). 3. 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). 4. The 9th and the 19th bytes are the product discrimination code. For details, refer to 2.12 “Product Discrimination Code”. 5. After sending the SUM, the device waits for the next operation command data. Number of Bytes Transferred Transfer Data from External Controller to TMP86FS27 Baud Rate Transfer Data from TMP86FS27 to External Controller BOOT ROM 1st byte 2nd byte Matching data (5AH) − 9600 bps 9600 bps − (Baud rate auto set) OK: Echo back data (5AH) Error: Nothing transmitted 3rd byte 4th byte Baud rate modification data (See Table 2.4.1) − 9600 bps 9600 bps − OK: Echo back data Error: A1H × 3, A3H × 3, 62H × 3 (Note 1) 5th byte 6th byte Operation command data (C0H) − Changed new baud rate Changed new baud rate − OK: Echo back data (C0H) Error: A1H × 3, A3H × 3, 63H × 3 (Note 1) 7th byte Changed new baud rate 3AH Start mark 8th byte Changed new baud rate 0AH The number of transfer data (from 9th to 18th byte) 9th byte Changed new baud rate 02H Length of address (2 bytes) 10th byte Changed new baud rate 03H Reserved data 11th byte Changed new baud rate 00H Reserved data 12th byte Changed new baud rate 00H Reserved data 13th byte Changed new baud rate 00H Reserved data 14th byte Changed new baud rate 01H The number of ROM block (1 block) 15th byte Changed new baud rate 10H First address of ROM (Upper 8 bits) 16th byte Changed new baud rate 00H First address of ROM (Lower 8 bits) 17th byte Changed new baud rate FFH End address of ROM (Upper 8 bits) 18th byte Changed new baud rate FFH End address of ROM (Lower 8 bits) 19th byte Changed new baud rate ECH Checksum of transferred data (from 9th to 18th byte) 20th byte (Wait for the next operation) (Command data) Changed new baud rate − |
