The command data to be "written" in the "PHYSICAL WRITE" command only contains the
command identifier "Reset DISA bit".
If the "DISA" bit of the optical reader has been reset, the command receives positive
acknowledgment. If it was already reset, this command has no effect but is nevertheless
positively acknowledged.
The "PHYSICAL WRITE" command must specify the length "0x01" ("CMD_STRUCT.Length
= 0x01"); otherwise, the command receives a negative acknowledgment.
