MPC5643L goes into DRUN mode after wakeup from Halt

Hi i'm running into an issue with the MPC5643L where the MCU switches to DRUN mode after wakeup from Halt0. The MCU was originally in RUN0 mode before switching to Halt0 for low power mode. The wakeup is triggered by a timer interrupt.

 

Prior to Halt0 request

ME_GS: 0x441f0074

 

After a timer interrupt wakes up the MCU:

ME_GS: 0x341f0074

ME_DMTS:0x40000000

 

Any ideas?

 

Thanks.
