FTM Fault Detection Inputs in KV31

[soerenbirth]

Hey there,

i have a  question about FTM Fault in MKV31F512VLL12 reference manual. As depicted above the chip configuration chapter has more fault detection input than the SIM_SOPT4 has bits for. Which one is correct?

Best regards

Sören

Hello Sören,

I suppose that both chapters are correct, because in SIM_SOPT4 register you can choose fault detection input between two possible options (fault pin or CMP), for example FTM1_FAULT0.

Even, FTM1_FAULT1 is hardwired to CMP1 output, thus, you are not able to change Fault input. There is not required changes in register.

best regards,

M.
