Now, the customer uses mainly Cortex-M4 in PSoC63.
So, he wants Cortex-M0+ to turn in deepsleep when it is unused.
So, we think if using following API will be able to do what he want.
However, even with the API, reduced value in power consumption is less than 0.1 mA.
Is this correct as a result of using the API?
If No, what should we check?
Hello. You will only see a significant current reduction if both CPUs go to deep-sleep, so all the high-frequency clocks will turn off (HFCLKx).
If the CM4 can't go to deep-sleep, try to at least call the Cy_SysPm_Sleep() API on CM4 as often as possible.
