Description
Number of retry attempts following a fault condition. If the fault persists after the programmed
number of attempts, the output is disabled and remains off until the fault is cleared. A fault
condition can be cleared by a reset, a power-off/power-on sequence, or a loss of bias power. The
time between restart attempts is specified by Delay Time 2 (Bits[2:0]).
