35.3.23 FTM Fault Input Polarity (FTMx_FLTPOL)
This register defines the fault inputs polarity.
Addresses: FTM0_FLTPOL is 4003_8000h base + 88h offset = 4003_8088h
FTM1_FLTPOL is 4003_9000h base + 88h offset = 4003_9088h

FTMx_FLTPOL field descriptions
Field Description
31–4
Reserved
This read-only field is reserved and always has the value zero.
3
FLT3POL
Fault Input 3 Polarity
Defines the polarity of the fault input.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0 The fault input polarity is active high. A one at the fault input indicates a fault.
1 The fault input polarity is active low. A zero at the fault input indicates a fault.
2
FLT2POL
Fault Input 2 Polarity
Defines the polarity of the fault input.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0 The fault input polarity is active high. A one at the fault input indicates a fault.
1 The fault input polarity is active low. A zero at the fault input indicates a fault.
1
FLT1POL
Fault Input 1 Polarity
Defines the polarity of the fault input.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
