OVM information read
Using this packet, the comparison results between OVM detection voltage set by operation mode setting packet
and the each voltage across constant-current output terminal can be read by the individual constant-current
output terminals.
For individual IDs, each flag is information for each constant-current output for each specified device ID.
However for common ID devices, the ORed information for constant-current output terminals of devices is
connected in series. Data sent from the controller should be 0 as a dummy data except for ID and CMD. If the
flag is 1, it is passed through.
