1 = Pin for corresponding analog channel is configured in Digital mode; I/O port read enabled
0 = Pin configured in Analog mode; I/O port read disabled, A/D samples pin voltage
Legend:
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
