ADC Interrupt flag. This bit must be cleared with software.
0 = No interrupt request
1 = The AINTF flag is set when ADSF goes from '0' to '1.' Interrupts CPU when
both AINTF and AINTEN are set to '1.'
ADC Interrupt Enable
0 = ADC interrupt is disabled
1 = ADC interrupt is enabled
ADC Enable Bit
0 = ADC shut off and consumes no operating current
1 = Enable ADC. After ADC is enabled, 16ms of calibration is needed before
ADST Bit is set.
