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 15-4 Unimplemented: Read as ‘0’
bit 3-0 ANSA<3:0>: Analog Select Control bits
1 = Digital input buffer is not active (use for analog input)
0 = Digital input buffer is active
