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.
