Description
6,4-0
FIF[5:0]
Fault m Interrupt Flag — This flag is set after the required number of samples have been detected after an edge
to the active level
(1)
on the FAULTm input. Writing a logic one to FIFm clears it. Writing a logic zero has no effect.
If a set flag is attempted to be cleared and a flag setting event occurs in the same cycle, then the flag remains
set. The fault protection is enabled when FENm 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 FAULTm input
1 Fault on the FAULTm input
Note: Clearing FIFm satisfies pending FIFm CPU interrupt requests.
m is 0, 1, 2, 3, 4 and 5.
1. The active input level may be defined or programmable at SoC level. The default for internally connected resources is active-
high. For availability and configurability of fault inputs on pins refer to the device overview section.
