Question

spc582b, wkpu RAM retention

I am developing an spc582bxx microcontroller using AutoDevKit Studio.

The device needs to wake up from sleep (standby 0) via wkpu, and RAM data must be preserved when not in por mode.

Therefore, I set the MC_PCU.PCONF2.B.STBY0 register before entering sleep.

However, looking at the generated boot code, it appears to clear all RAM areas during booting.

Is there a boot code sample that preserves RAM data during wake-up via wkpu?

I look forward to your reply.

Thank you.
