Comparator Output Logic State Bit.
Response Time.
5 μs response time typical for large signals (2.5 V differential).
17 μs response time typical for small signals (0.65 mV differential).
Reserved.
Reserved.
3 μs response time typical for any signal type.
Comparator Hysteresis Bit.
Comparator Output Rising Edge Interrupt.
Comparator Output Falling Edge Interrupt.
REF
When low, the comparator output is high when the positive input (CMP0) is above the negative
input (CMP1).
When high, the comparator output is high when the positive input is below the negative input.
Set by user to have a hysteresis of about 7.5 mV.
Cleared by user to have no hysteresis.
Set automatically when a rising edge occurs on the monitored voltage (CMP0).
Cleared by user by writing a 1 to this bit.
Set automatically when a falling edge occurs on the monitored voltage (CMP0).
Cleared by user.
Set by user to enable the comparator.
Cleared by user to disable the comparator.
