cc1110 pm2 with multiple interrupts

I would like to put the cc1110 into PM2. It needs to wake up 1 per minute via sleep timer. No problem I have that running from the app note. I also need to count events using interrupts from 2 of the pins. According to the documentation the LS clock will awake as and RC clock. Assuming the wakeup clock was clocked by the 32khz xtal, this will change by and interrupt from one of the pins. Can I change to xtal without distupting the sleep timer? Can timer and pin interrupts both exist in PM2?

    Hi.

    The datasheet seems wrong in that matter. The 32 kHz xtal will remain as the selected source until the user tells it differently. The sleeptimer runs un-disturbed.

    Both sleeptimer and pin interrupts can wake the chip up from PM2. Regular timer interrupts (Timer 1,2,3 & 4) can not.
