Fault input disable FTM output for KV11

For KV11, the fault input is used for disable PWM output, could you help answer the following two questions?

1. If FTM0_FLT0 is enabled, all channels of FTM0 output are disabled or only FTM0_CH0/FTM0_CH1 are disabled?

2. Whether FTM1_FLT0 can be used to disable PWM output of FTM0_CH0/FTM0_CH1?

Thanks!

Hi Li Yang,

According to the reference manual, there are two group of bits for configuring the fault control feature of channels.

The FAULTM[1:0] is used to configure the general fault control mode, and the FAULTENn bit is used to enable or disable the fault control feature of the specific pair of the channels.

So it's available to enable one pair of channels in the FTM module.
Have a great day,
Ping
