Hibernation Module
interrupt status can be found by calling ROM_HibernateIntStatus(). In the interrupt handler, all
pending interrupts must be cleared. Use the ROM_HibernateIntClear() function to clear pending
interrupts.
Finally, once the module is appropriately configured, the state saved, and the software applica-
tion is ready to hibernate, call the ROM_HibernateRequest() function. This will initiate the se-
quence to remove power from the processor. At a power-on reset, the software application can
use the ROM_HibernateIsActive() function to determine if the Hibernation module is already ac-
tive and therefore does not need to be enabled. This can provide a hint to the software that
the processor is waking from hibernation instead of a cold start. The software can then use the
ROM_HibernateIntStatus() and ROM_HibernateDataGet() functions to discover the cause of the
wake and to get the saved system state.
