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 15-9

Unimplemented: Read as ‘0’

bit 8-0

CSS<8:0>: ADC Input Scan Selection bits
1 = Select ANx for input scan
0 = Skip ANx for input scan

Note 1: On devices without 9 analog inputs, all AD1CSSL bits can be selected by the user application. However,

inputs selected for scan without a corresponding input on device converts V

REFL

2: CSSx = ANx, where x = 0 through 8.

Unimplemented: Read as ‘0’

bit 8-0

PCFG<8:0>: ADC Port Configuration Control bits
1 = Port pin in Digital mode, port read input enabled, ADC input multiplexer connected to AV

0 = Port pin in Analog mode, port read input disabled, ADC samples pin voltage

Note 1: On devices without 9 analog inputs, all PCFG bits are R/W by user software. However, the PCFG bits are

ignored on ports without a corresponding input on device.

2: PCFGx = ANx, where x = 0 through 8.
3: The PCFGx bits have no effect if the ADC module is disabled by setting ADxMD bit in the PMDx Register.

In this case, all port pins multiplexed with ANx will be in Digital mode.
