‘1’ = Bit is set

bit 15-0
PCFG<31:16>: 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: On devices without 32 analog inputs, all PCFG bits are R/W by user. However, PCFG bits are ignored on
ports without a corresponding input on device.
2: ADC2 only supports analog inputs AN0-AN15; therefore, no ADC2 high port Configuration register exists.
3: PCFGx = ANx, where x = 16 through 31.
4: PCFGx bits will 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.

On devices without 16 analog inputs, all PCFG bits are R/W by user. However, PCFG bits are ignored on
ports without a corresponding input on device.
On devices with 2 analog-to-digital modules, both AD1PCFGL and AD2PCFGL will affect the configuration
of port pins multiplexed with AN0-AN15.
PCFGx = ANx, where x = 0 through 15.
PCFGx bits will 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.
