Legend:

HC = Hardware Clearable bit U = Unimplemented bit, read as ‘0’

R = Readable bit

W = Writable bit

HSC = Hardware Settable/Clearable bit

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

HS = Hardware Settable bit

bit 15-13

Unimplemented: Read as ‘0’

bit 12-8

CHNL<4:0>: Input Channel Number bits

If the comparator has detected an event for a channel, this channel number is written to these bits.

11111 = Reserved

•

10110 = Reserved

10101 = AN21

10100 = AN20

•

00001 = AN1

00000 = AN0

bit 7

CMPEN: Comparator Enable bit

1 = Comparator is enabled

0 = Comparator is disabled and the STAT status bit is cleared

bit 6

IE: Comparator Common ADC Interrupt Enable bit

1 = Common ADC interrupt will be generated if the comparator detects a comparison event

0 = Common ADC interrupt will not be generated for the comparator

bit 5

STAT: Comparator Event Status bit

This bit is cleared by hardware when the channel number is read from the CHNL<4:0> bits.

1 = A comparison event has been detected since the last read of the CHNL<4:0> bits

0 = A comparison event has not been detected since the last read of the CHNL<4:0> bits

bit 4

BTWN: Between Low/High Comparator Event bit

1 = Generates a comparator event when ADCMPxLO ≤ ADCBUFx < ADCMPxHI

0 = Does not generate a digital comparator event when ADCMPxLO ≤ ADCBUFx < ADCMPxHI

bit 3

HIHI: High/High Comparator Event bit

1 = Generates a digital comparator event when ADCBUFx ≥ ADCMPxHI

0 = Does not generate a digital comparator event when ADCBUFx ≥ ADCMPxHI

bit 2

HILO: High/Low Comparator Event bit

1 = Generates a digital comparator event when ADCBUFx < ADCMPxHI

0 = Does not generate a digital comparator event when ADCBUFx < ADCMPxHI

bit 1

LOHI: Low/High Comparator Event bit

1 = Generates a digital comparator event when ADCBUFx ≥ ADCMPxLO

0 = Does not generate a digital comparator event when ADCBUFx ≥ ADCMPxLO

bit 0

LOLO: Low/Low Comparator Event bit

1 = Generates a digital comparator event when ADCBUFx < ADCMPxLO

0 = Does not generate a digital comparator event when ADCBUFx < ADCMPxLO
