Hi ,


We wanted to start a STM timer just before entering into STBY mode in MPC5748G. This is to implement a periodic check in the SLEEP mode. Could you please answer following queries about this .


1. During the timeout , to service the STM interupt whether power mode will be changed automatically to DRUN on a timer interrupt?

2. STM timer is clocked by 80MHZ in run mode, what will be the clock frequency and clock source in STBY mode, is it configurable?

3. In case STM is not active in STBY which other timer can be used for period interrupt.
