Version 1.2
P3: number of data bytes sent to the coupler.
Ack. : coupler acknowledgement. It is always equal to the command code, except when
an error occurs. If Acknowledgement value is different than instruction byte, then the
received byte is the first byte of a status error code coded on 2 bytes.
Data : data sent by host to the coupler. Size of data array has to be P3.
Status word : 90 00h if correct / error code.
Error : If the Acknowledgement value is different than the instruction byte, then the received
byte is the first byte of a status error code coded on 2 bytes.
