 PDMA operation.

Analog Comparator (ACMP)

 Two rail-to-rail Analog Comparators.

 Supports four multiplexed I/O pins at positive input.

 Supports I/O pins, band-gap, DAC output, and 16-level Voltage

divider from AVDD or VREF at negative input.

 Supports four programmable propagation speeds for power saving.
