We are going into sleep mode for the processor. We are using Zephyr and sdk 2.3. We also are keeping a running count of seconds and synching that once a day with a modem. Is there a timer or counter that is used by Zephyr so that we can get a count of system ticks we are are asleep. We tried using ostimer tick, but it appears to be off once we wake from sleep. THis is a 5340 so we only have one RTC type counter.
