bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-14

PVCFG<1:0>:

Converter Positive Voltage Reference Configuration bits

= Unimplemented, do not use

=External VREF+

=AVDD

bit 13

NVCFG0:

Converter Negative Voltage Reference Configuration bits

=External VREF-

=AVSS

bit 12

OFFCAL:

Offset Calibration Mode Select bit

= Inverting and non-inverting inputs of channel Sample-and-Hold are connected to AVSS

= Inverting and non-inverting inputs of channel Sample-and-Hold are connected to normal inputs

bit 11

BUFREGEN:

A/D Buffer Register Enable bit

= Conversion result is loaded into the buffer location determined by the converted channel

= A/D result buffer is treated as a FIFO

bit 10

CSCNA:

Scan Input Selections for CH0+ During Sample A bit

= Scan inputs

= Do not scan inputs

bit 9-8

Unimplemented:

Read as ‘0’

bit 7

BUFS:

Buffer Fill Status bit(1)

= A/D is filling the upper half of the buffer; user should access data in the lower half

= A/D is filling the lower half of the buffer; user should access data in the upper half

bit 6-2

SMPI<4:0>:

Interrupt Sample/DMA Increment Rate Select bits

When DMAEN = 1:

0001

= For 2-channel DMA A/D operation

0000

= For 1-channel DMA A/D operation

When DMAEN = 0:

Selects the number of sample/conversions per each interrupt

11111

= Interrupt/address increment at the completion of conversion for each 32nd sample

11110

= Interrupt/address increment at the completion of conversion for each 31st sample



00001

= Interrupt/address increment at the completion of conversion for every other sample

00000

= Interrupt/address increment at the completion of conversion for each sample

Note 1:

These bits are only applicable when the buffer is used in FIFO mode (BUFREGEN = 0). In addition, BUFS

is only used when BUFM = 1.
