This register can only be written if the bits WPSWS5 and WPHWS5 are cleared in
page
Only the first 4 bits (number of fault input pins) of fields FPE0, FPE1, FPE2 and FPE3 are significant.
• FPEx: Fault Protection Enable for channel x (fault input bit varies from 0 to 3)
For each field bit y (fault input number):
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 bit has been previously configured to its final value in
932

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.
