CMP_CR0 field descriptions (continued)Field Description000 Filter is disabled. If SE = 1, then COUT is a logic zero (this is not a legal state, and is notrecommended). If SE = 0, COUT = COUTA.001 1 consecutive sample must agree (comparator output is simply sampled).010 2 consecutive samples must agree.011 3 consecutive samples must agree.100 4 consecutive samples must agree.101 5 consecutive samples must agree.110 6 consecutive samples must agree.111 7 consecutive samples must agree.3–1ReservedThis field is reserved.This read-only field is reserved and always has the value 0.0HYSTCTRComparator hard block hysteresis controlDefines the programmable hysteresis level. The hysteresis values associated with each level is device-specific.

If a write to this register attempts to set both, then SE is setand WE is cleared. However, avoid writing ones to both bit locations because this "11" case is reservedand may change in future implementations.0 Sampling mode not selected.1 Sampling mode selected.6WEWindowing EnableAt any given time, either SE or WE can be set.
