register, the current ADCMODE bits are preserved, that is,
they are not reset to default state. Upon a subsequent
resumption of normal operating mode, the ADCs restarts
the selected operation defined by the ADCMODE register.
Once ADCMODE has been written with a calibration
mode, the RDY0/1 (ADuC845 only) bits (ADCSTAT) are
reset and the calibration commences. On completion, the
