Sets or returns automatic fault recovery in the form x, where:
x = 1 (DEFAULT)
NOTE: The LPOD output automatically mute if the BUC Lock Detect fault condition occurs. If auto fault recovery is
enabled, it will cause the output return to its pre-fault mute condition if all faults are cleared. If disabled, the
output will remain muted even if all faults are cleared
