1. Typical hysteresis is measured with input voltage range limited to 0.6 to VDD-0.6V.
2. Comparator initialization delay is defined as the time between software writes to change control inputs (Writes to DACEN,
VRSEL, PSEL, MSEL, VOSEL) and the comparator output settling to a stable level.
3. 1 LSB = Vreference/64
