17.2.11 ADC REGISTER DEFINITIONS
The following registers are used to control the
operation of the ADC.
Note: Analog pin control is determined by the
ANSELx registers (see Register 10-2)

GO/DONE: A/D Conversion Status bit
1 = A/D conversion cycle in progress. Setting this bit starts an A/D conversion cycle.
This bit is automatically cleared by hardware when the A/D conversion has completed.
0 = A/D conversion completed/not in progress
