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
This bit is automatically cleared by hardware when the A/D conversion has completed.
0 = A/D conversion completed/not in progress
bit 0
ADON:
ADC Enable bit
1 = ADC is enabled
0 = ADC is disabled and consumes no operating current
0 = ADC is disabled and consumes no operating current
