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

OFFCAL: Input Offset Calibration Mode Select bit

1 = Enable Offset Calibration mode

Positive and negative inputs of the sample and hold amplifier are connected to VREFL

0 = Disable Offset Calibration mode

The inputs to the sample and hold amplifier are controlled by AD1CHS or AD1CSSL

Unimplemented: Read as ‘0’

CSCNA: Input Scan Select bit

1 = Scan inputs

0 = Do not scan inputs

Unimplemented: Read as ‘0’

BUFS: Buffer Fill Status bit

Only valid when BUFM = 1.

1 = ADC is currently filling buffer 0x8-0xF, user should access data in 0x0-0x7

0 = ADC is currently filling buffer 0x0-0x7, user should access data in 0x8-0xF

Unimplemented: Read as ‘0’

SMPI<3:0>: Sample/Convert Sequences Per Interrupt Selection bits

1111 = Interrupts at the completion of conversion for each 16th sample/convert sequence

1110 = Interrupts at the completion of conversion for each 15th sample/convert sequence

•

•

•

0001 = Interrupts at the completion of conversion for each 2nd sample/convert sequence

0000 = Interrupts at the completion of conversion for each sample/convert sequence

BUFM: ADC Result Buffer Mode Select bit

1 = Buffer configured as two 8-word buffers, ADC1BUF7-ADC1BUF0, ADC1BUFF-ADCBUF8

0 = Buffer configured as one 16-word buffer ADC1BUFF-ADC1BUF0

ALTS: Alternate Input Sample Mode Select bit

1 = Uses Sample A input multiplexer settings for first sample, then alternates between Sample B and

Sample A input multiplexer settings for all subsequent samples

0 = Always use Sample A input multiplexer settings
