Hello,i am working on configuating the etpuc channel 15 as a hall sensor input function,this hall sensor input is 0 and 1 signal with 10k frequency,so it need IGF module refered channel to match up.I check the datasheet of the chip MPC5777C but found that the IGF did not has the corresponding channel with the etpuc15.I want to confirm it ,also please give me some advice to solve this issue without changing the hardware board.Thanks!

Hi,

Indeed, eTPUC_15 channel can't be filtered by IGF module, but eTPU_CH15 still can capture input signal without IGF.

you can try to enable eTPU channel input filters function to avoid hardware changes. Please refer UM chapter: Enhanced Digital Filter - EDF
