Can KBI wake up MCU in stop2?

Hi,

The datasheet isn't clear about if KBI can wake up MCU in stop2.

MCU is MC9S08LC60.

Have you ever experience this?

Thank you.

Hi,

When in STOP2 the only way out is by asserting the RESET/IRQ or by an RTI. It is not possible to use a KBI to exit stop2 (although it is possible to exit stop3 using a KBI). I have tried this before and was unable to use KBI, but was successful with an IRQ.

It really can't wake up in stop2 with KBI.

So I have to use stop3 mode for my application.

Thank you.
