Chapter 16 Low Leakage Wakeup Unit (LLWU)
16.1.2.4 Debug mode
When the chip is in debug mode and then enters LLS or a VLLSx mode, no debug logic
works in the fully functional low leakage mode. Upon an exit from the LLS or VLLSx
mode, the LLWU becomes inactive. If the exit is from a VLLSx mode, the wakeup did
not occur via the RESET pin, and the SIM's SOPT4[VLLDBGREQ] bit is set to 1, the
debug logic becomes active again upon the exit from the VLLSx mode.
