condition. When TWARN is asserted (set to 0) for a period of time greater than 400 ms, the
power control block forces a -3 dB output limit (determined by TWOCL in the coefficient
RAM) to the modulation limit in an attempt to eliminate the thermal warning condition. Once
the thermal warning output limit adjustment is applied, it remains in this state until reset,
unless FDRB = 0.

The on-chip STA335W 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 tri-state output (setting it to 0 which
directs the power output block to begin recovery), holds it at 0 for period of time in the range
of 0.1 ms to 1 second as defined by the fault-detect recovery constant register (FDRC
registers 0x29-0x2A), then toggles it back to 1. This sequence is repeated as log as the fault
indication exists. This feature is enabled by default but can be bypassed by setting the
FDRB control bit to 1.
