Operation
Always reads as a zero
0: The MIC3003 is disabling the laser
1: The laser is enabled to operate
0: No Fault Comparator receive power fault
1: The Fault Comparator has detected a receive power fault
1 = The interrupt is asserted
0 = No pending interrupt.
1 = APC saturation fault detected
0 = Normal operation.
1 = IBIAS fault detected
0 = Normal operation
1 = Registered transmit power fault
0 = normal operation
1 = high; 0 = low
