ADC Usage without CSL

We are using the S12ZVM128 chip to control BLDC motors.

We already have CSL setup for ADC for motor control requirements. This is working fine.

We have 2 ADC1 inputs that are required to be polled at low frequency and when the motor is not running.

We do NOT want to change the CSL/RVL address due to several reasons.

We do NOT want to add to the CSL because we do not want unnecessary conversions when motor is running.


We could add to CSL while keeping the previous entry set as CMD_SEL[1:0] as 1,1 but then we can't reach this new entry and also we can't set the index as ADCCIDX is RO.


Is there any way to achieve the above or just run an Adhoc ADC command without running through the CSL ? Already ADCFLWCTL is set for DUAL access on both ADC's
