Sampled, Filtered (# 4B): sampling point internally derivedThe only difference in operation between Sampled, Non-Filtered (# 3B) and Sampled,Filtered (# 4B) is that now, C0[FILTER_CNT]>1, which activates filter operation.39.7.5 Windowed mode (#s 5A & 5B)The following figure illustrates comparator operation in the Windowed mode, ignoringlatency of the analog comparator, polarity select, and window control block. It alsoassumes that the polarity select is set to non-inverting state.NOTEThe analog comparator output is passed to COUTA only whenthe WINDOW signal is high.In actual operation, COUTA may lag the analog inputs by up to one bus clock cycle plusthe combinational path delay through the comparator and polarity select logic.CMP functional modesMWCT101xS Series Reference Manual, Rev. 3, 07/20191062 NXP Semiconductors
