20.6.5 Product ID Code Output Mode (Operation Command: C0H)

Table 20-11 shows product ID code output mode process.

Note: “xxH

× 3” indicates that the device enters the halt condition after sending 3 bytes of xxH. For details, refer to " 20.7 Error

Code ".

Description of Product ID code output mode

1. The 1st through 4th bytes of the transmitted and received data contain the same data as in the flash

memory writing mode.

2. The 5th byte of the received data contains the product ID code output mode command data (C0H).

3. When the 5th byte contains the operation command data shown in Table 20-6, the device echoes back

the value which is the same data in the 6th byte position of the received data (in this case, C0H). If the

5th byte data does not contain the operation command data, the device enters the halt condition after

sending 3 bytes of operation command error code (63H).

4. The 9th through 19th bytes contain the product ID code. For details, refer to " 20.11 Product ID Code
