Setting a pin to an analog input disables the digital input buffer. The corresponding TRIS bit should be set
for an input and cleared for an output (analog or digital). The ANSx bits directly correspond to the ANx pins
(e.g., ANS0 = AN0, ANS1 = AN1, etc.). Unused ANSx bits are to be read as ‘0’.
ANS7 through ANS5 are available only on PIC18F4331/4431 devices.
