00 = F
01 = F
10 = F
11 = F
Unimplemented: Read as '0'.
CHS1:CHS0: Analog Channel Select bits
00 = channel 0, (AN0)
01 = channel 1, (AN1)
10 = channel 2, (AN2)
11 = channel 3, (AN3)
GO/DONE: A/D Conversion Status bit
If ADON = 1
1 = A/D conversion in progress (setting this bit starts the A/D conversion)
0 = A/D conversion not in progress (This bit is automatically cleared by hardware when the
ADIF
1 = conversion is complete (must be cleared in software)
0 = conversion is not complete
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shutoff and consumes no operating current
