Hello guys,

When use tickless idle in RTOS, I see my ADC reading I get from raw data all are fix 4041!
It seems maybe ADC could be powered down in automatic light sleep.

Is it possible to force SARADC do not power down in auto light sleep?

As you see. I didn't check the option below,
[uncheck]Power down Digital Peripheral in light sleep (EXPERIMENTAL)

If power management lock can be the only one solution, does this mean that the system will never work automatic light-sleep? However, ADC have to be reinitialized each time wake-up?

Make me confuse.
