Comparator Characteristics

Note 1. Period from when the comparator input channel is switched until the switched result reflects in its output.

Note 2. Period from when comparator operation is enabled (CPMCTL.HCMPON = 1) until the comparator satisfies the

DC/AC characteristics.

Note 1. In window mode, be sure to satisfy the following condition: Vref1 - Vref0

 0.2 V.
