This register can only be written if bits WPSWS5 and WPHWS5 are cleared in the “PWM Write Protection Status Register”
.
Only the first 8 bits (number of fault input pins) of fields FPE0, FPE1, FPE2 and FPE3 are significant.
• FPEx: Fault Protection Enable for channel x
For each field bit y (fault input number):
0: Fault y is not used for the Fault Protection of channel x.
1: Fault y is used for the Fault Protection of channel x.
CAUTION: To prevent an unexpected activation of the Fault Protection, the bit y of FPEx field can be set to ‘1’ only if the
corresponding FPOL field has been previously configured to its final value in “PWM Fault Mode Register” .
