2. Test
This is a command to perform a test on host communications which allows communication tests on an
applicable address.
As is the case with the command Read, the response B is returned via the response A and command B.
The response B has the same contents as those of command A.
When a command is received normally, the ACK
flag of the Status box is received as '1'.
