bit 7 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 15-0 PCFG<31:16>: ADC Port Configuration Control bits
1 = Port pin in Digital mode, port read input enabled, ADC input multiplexer connected to AV
SS
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 port Configuration register exists.
3: PCFGx = ANx, where x = 16 through 31.

bit 15-0 PCFG<15:0>: ADC Port Configuration Control bits
1 = Port pin in Digital mode, port read input enabled, ADC input multiplexer connected to AV
SS
0 = Port pin in Analog mode, port read input disabled, ADC samples pin voltage
Note 1: 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.
2: On devices with two analog-to-digital modules, both AD1PCFGL and AD2PCFGL will affect the
configuration of port pins multiplexed with AN0-AN15.
3: PCFGx = ANx, where x = 0 through 15.
