The ADC can generate an interrupt request when a conversion is completed. An interrupt
request that is pending when the ADC is disabled is not automatically cleared.
The Timer 0 count is captured for every ADC conversion. The capture of the Timer 0 count
occurs after the programmed sample time is complete for every conversion and stored in
the ADC Timer Capture register (ADCTCAP).
The reference buffer (RBUF) supplies the reference voltage for the ADC. When enabled,
the internal voltage reference generator supplies the ADC and the voltage is available on
the V
externally through the V
register.
The Internal Voltage Reference Generator provides the voltage (VR2) for the RBUF.
VR2 is 2 V.
