 Mode (1 byte) : A clock mode returned in reply to the supported clock mode inquiry.
 SUM (1 byte) : Checksum
Response H'06
 Response, H'06, (1 byte) : Response to the clock mode selection command
ACK will be returned when the clock mode matches.
Error
response H'91
ERROR
 Error response, H'91, (1 byte) : Error response to the clock mode selection command
 ERROR, (1 byte) : Error code
H'11 : Checksum error
H'22 : Clock mode error, that is, the clock mode does not match.
