31.10.6.1
Device Select
This command is used to specify the endian of developed software. Select a device code from among the device codes
obtained in the response to the support device inquiry command.
If the received device code matches the supported device, the MCU sends a response (46h).
If the device is not supported or the SUM of the received command does not match, the MCU sends an error response.
Command
10h
Size (1 byte): Number of characters of the device code (the value is always 04h)
Device code (4 bytes): Identification code to identify an endian of the developed software
(code in the response to the support device inquiry command)
SUM (1 byte): Value that is calculated so the sum of command data is 00h
Response
46h
Error response
90h
Error (1 byte): Error code
11h: SUM error
21h: Device code error
