being attached.. (TCK pin being forced low) Please refer to
[IOC:IOCFGn,.WU_CFG] for configuring the IO's as wakeup
sources. 0: Wakeup occurred from cold reset or brown out as seen
in RESET_SRC 1: A wakeup has occurred from SHUTDOWN Note:
This flag can not be cleared and will therefor remain valid untill
poweroff/reset
