CSS<12:0>: ADC Input Scan Selection bits
1 = Select ANx for input scan
0 = Skip ANx for input scan
Note 1: On devices without 13 analog inputs, all AD1CSSL bits can be selected by user application. However,
inputs selected for scan without a corresponding input on device converts VREF-.
2: CSSx = ANx, where x = 0 through 12.

PCFG<12:0>: ADC Port Configuration Control bits
1 = Port pin in Digital mode, port read input enabled, ADC input multiplexor connected to AVSS
0 = Port pin in Analog mode, port read input disabled, ADC samples pin voltage
Note 1:

3:
On devices without 13 analog inputs, all PCFG bits are R/W by user. However, PCFG bits are ignored on
ports without a corresponding input on device.
PCFGx = ANx, where x = 0 through 12.
PCFGX bits have no effect if 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.
