Hi,
When I set CCR1[SAMPLE_EN] to be 1, which clock source would be used?
Is the external signal source an actual pin input or is it set somewhere else?”

Hi @Jack_Hsu
When CCR1[SAMPLE_EN]=1, the WINDOW/SAMPLE signal acts as the Sampling Clock of the Filter Block. The external SAMPLE input signal is an output pulse generated via TRGMUX. See the LPCMP_Sample/Window input in the TRGMUX connectivity file attached to the S32K3xx Reference Manual, Rev. 8.
