I'm trying to use the HCS08LL16 to periodically wake from STOP2 using the time-of-day (TOD) module. It appears to sleep for 1 second the first time, but all remaining times only sleeps for about 200uS. Yes, I have port B bit 2 configured as an input and pullup enabled before entering STOP2. Yes, I check for PPDF after reset to determine if reset was due to wake from STOP2. Yes, I'm restoring port config before writing PPDACK.
I have this implemented and working on the QE128 (using RTC) , but cannot get to work on the LL16 (using TOD).
Anyone out there with an example or tips?
