Hi ,

I  want to wakeup kea128 through mscan wakeup interrupt.

First I trial mscan wakeup interrupt in mscan sleep mode(SLPRQ = 1 && SLPACK = 1), it can wakeup by wakeup interrupt.

However ,I try to make MSCAN entre sleep mode , setting wakeup interrupt bit and enable bit ,making KEA128 entre Sleep mode through WFI instruct ,I can't wakeup cpu through mscan wakeup interrupt.

Am i ingoring something?

Thanks.

I am not sure if you have slove this issue(Assumed Answered).

The MSCAN(Sleep mode) wake-up interrupt should be able to wakeup KEA128 from sleep(WAIT) mode.

It's one of the AWIC stop wakeup source listed in "Table 3-11. AWIC stop wakeup sources".
