All PWM trip levels are tristate
All PWM trip levels are defined by PT_LVL and PT_LVL_N
After power trip, PWMx outputs are set to one.
After power trip, PWMx outputs are set to zero.
After power trip, PWMx outputs are set to one.
After power trip, PWMx outputs are set to zero.
Power trip has been cleared.
This bit is set after power trip event.
