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.
