Hi, 

I have some question about the filter mode of TIM.

1. The up/down counter mode with rising edge, after F_OUT reaches High level, does the FLT_CNT decremented?

2. The Hold counter mode with rising edge, after F_OUT reaches High level, how does the FLT_CNT reset? If the cnt can't be reset, does it means the filter only can work one time?

The filter counter register FLT_CNT is incremented when the signal level on F_IN_SYNC is unequal to the signal level on F_OUT 

 

I think the FLT_CNT will stop increment after F_OUT = F_IN_SYNC and not reset to 0.

Hi, dw

Thank you for your reply. 

If the FLT_CNT act as your think, the Filter can only work one time. I don't think it's reasonable.

Hi Jamber,
