38.7.27 PWM Fault Protection Enable Register 1
Name: PWM_FPE1
Address: 0x4009406C
Access: Read-write
This register can only be written if the bits WPSWS5 and WPHWS5 are cleared in “PWM Write Protect Status Register” on
page 1039.
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 cha nnel 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 bit has been previously configured to its final value in “PWM Fault Mode Register” on page 1029.
