Reset Controller Module
The reset controller is provided to determine the cause of reset, assert the appropriate reset signals to the
system, and then to keep a history of what caused the reset. The Low Voltage Detection module, which
generates low-voltage detect (LVD) interrupts and resets, is implemented within the reset controller
module.

Seven sources of reset:
— External
— Power-on reset (POR)
— Watchdog timer
— Phase locked-loop (PLL) loss of lock
— PLL loss of clock
— Software
— LVD reset
Software-assertable RSTO pin independent of chip reset state
Software-readable status flags indicating the cause of the last reset
LVD control and status bits for setup and use of LVD reset or interrupt
