STM32WL55: interrupting CPU2

On the STM32WL55 MCUs, is it possible to have the ADC interrupt go only to the Cortex-M0+(CPU2)?   I have a situation where I would like to trigger CPU2 with interrupts from the ADC, but I don't want to trigger the ADC interrupt for CPU1. Is this possible on the STM32WL55? If that's not possible, what's the next best way to simulate this desired behavior?

Hello @AJ_1 

As you can see on the Table 90 of the RM0453, you can configure the ADC interrupt to go to the CPU2. More details are explained on the Reference Manual.

Best Regards.
