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 2.19.5,
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 7th and the 19th bytes are the product discrimination code. For details, refer
to 2.19.12 “Product Discrimination Code”.
5. After sending the SUM, the device waits for the next operation command data.
