ADuC7061 self-offset calibration

I need your help with ADuC7061. Does self-offset calibration work on the
auxiliary ADC of ADuC7061, too? We tested the gain and offset calibration – it
works well on the primary ADC but we need the self-offset calibration on the
auxiliary ADC as well.


Seeing as there is only one ADCMDE register which enables calibration I believe
that when you calibrate it will be done on whichever ADC is enabled. So if both
are enable calibration is done at the same time for both ADCs.

Saying that though I would recommend that you enable the primary ADC, perform
calibration, then disable the primary ADC and enable the secondary ADC and
perform calibration on it the same way as on the primary.
