Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 1-0

VCFG<1:0>: A/D VREF+ and A/D VREF- Source Selection bits

00 = VREF+ = AVDD, VREF- = AVSS (AN2 and AN3 are analog inputs or digital I/O)

01 = VREF+ = External VREF+, VREF- = AVSS (AN2 is an analog input or digital I/O)

10 = VREF+ = AVDD, VREF- = External VREF- (AN3 is an analog input or digital I/O)

11 = VREF+ = External VREF-, VREF- = External VREF-

Unimplemented: Read as ‘0’

FIFOEN: FIFO Buffer Enable bit

1 = FIFO is enabled

0 = FIFO is disabled

BFEMT: Buffer Empty bit

1 = FIFO is empty

0 = FIFO is not empty (at least one of four locations has unread A/D result data)

BFOVFL: Buffer Overflow bit

1 = A/D result has overwritten a buffer location that has unread data

0 = A/D result has not overflowed

ADPNT<1:0>: Buffer Read Pointer Location bits

Designates the location to be read next.

00 = Buffer Address 0

01 = Buffer Address 1

10 = Buffer Address 2

11 = Buffer Address 3
