The ADC can generate an interrupt request when a conversion has been completed. An
interrupt request that is pending when the ADC is disabled is not cleared automatically.
The reference buffer, RBUF, supplies the reference voltage for the ADC. When enabled,
the internal voltage reference generator supplies the ADC. When RBUF is disabled, the
ADC must have the reference voltage supplied externally through the V
package. RBUF is controlled by the REFEN bit in the ADC control register.
The internal voltage reference generator provides the voltage VR2, for the RBUF. VR2 is
2 V.
A user can perform calibration and store the values into Flash, or the user code can
perform a manual offset calibration. There is no provision for manual gain calibration.
The ADC control registers are defined in the following paragraphs.
The ADC control register 0 initiates the A/D conversion and provides ADC status
information. See
