RM44L920: ADC magnitude compare configuration

Richard Derman2

Part Number: RM44L920

I am currently the ADC Magnitude Compare interrupts by putting all 3 of the available compares in a single conversion group (2). This has been working well.

I recently came across a line in the RM44 data sheet which says that only one Magnitude Threshold Compare per group is available. Is the data sheet incorrect, or did I get "lucky" with a feature that may not always be supported?

Hello,

You can have all three of the magnitude threshold compare interrupts generated based on conversions from a single group. This is actually the expected use case, where a single group is configured for continuous conversions with the conversion results only used in the magnitude threshold compare logic. The other conversion groups can then "cut in" for their single conversion sequences as and when required.
