CMPON: A/D Operating Mode bit
1 = Comparator module is enabled
0 = Comparator module is disabled (reduces power consumption)
Unimplemented: Read as ‘0’
CMPSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode.
0 = Continue module operation in Idle mode.
If a device has multiple comparators, any CMPSIDL bit set to ‘1’ disables ALL comparators while in
Idle mode.
Reserved: Read as ‘0’
INSEL<1:0>: Input Source Select for Comparator bits
00 = Select CMPxA input pin
01 = Select CMPxB input pin
10 = Select CMPxC input pin
11 = Select CMPxD input pin
EXTREF: Enable External Reference bit
1 = External source provides reference to DAC
0 = Internal reference sources provide source to DAC
Reserved: Read as ‘0’
CMPSTAT: Current State of Comparator Output Including CMPPOL Selection bit
Reserved: Read as ‘0’
CMPPOL: Comparator Output Polarity Control bit
1 = Output is inverted
0 = Output is non inverted
RANGE: Selects DAC Output Voltage Range bit
1 = High Range: Max DAC value = AVDD / 2, 2.5V @ 5 volt VDD
0 = Low Range: Max DAC value = Internal Reference, 1.2V +-1%
