ADC does not release the fast clock request in between periodical triggers

Revisions Affected

Rev C

Details

When the ADC is set up in repeat mode and triggered periodically via the event fabric, it does not release its fast clock request in between triggers. IF so, the ADC will hold the clock request AND consume extra power.

Workaround

Configuring the ADC in single mode (run to completion with ADC disabling at end of channel/sequence), AND THEN using a software interrupt at the end of the ADC sequence to re-enable the ADC to wait for the next trigger.
