Fault detect recovery bypass

The on-chip STA333ML power output block provides feedback to the digital controller using

inputs to the power control block. The FAULT input is used to indicate a fault condition (either

over-current or thermal). When FAULT is asserted (set to 0), the power control block

attempts a recovery from the fault by asserting the tristate output (setting it to 0 which

directs the power output block to begin recovery), holds it at 0 for 1 ms and then toggles it

back to 1. This sequence is repeated for as long as the fault exists.
