Fault x Pin Flag — This flag is set after the required number of samples have been detected after a rising edge
on the FAULTx pin. Writing a logic one to FFLAGx clears it. Writing a logic zero has no effect. The fault protection
is enabled when FPINEx is set even when the PWMs are not enabled; therefore, a fault will be latched in,
requiring to be cleared in order to prevent an interrupt.
0 No fault on the FAULTx pin.
1 Fault on the FAULTx pin.
Note: Clearing FFLAGx satisfies pending FFLAGx CPU interrupt requests.
where x is 0, 1, 2 and 3.
Fault x Qualifying Samples — This field indicates the number of consecutive samples taken at the FAULTx pin
to determine if a fault is detected. The first sample is qualified after two bus cycles from the time the fault is
present and each sample after that is taken every four bus cycles. See
where x is 0, 1, 2 and 3.
