38.7.27 PWM Fault Protection Enable Register
Name:
PWM_FPE
Address:
0x4002006C
Access:
Read-write
This register can only be written if the bits WPSWS5 and WPHWS5 are cleared in
Only the first 6 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 5)
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 corre-
sponding FPOL bit has been previously configured to its final value in
