The cold start-up/warm start-up determination function uses the CWR bit in the RSTFR register to determine cold
start-up (reset process) at power-on and warm start-up (reset process) when a reset occurred during operation.
The CWR bit is set to 0 (cold start-up) at power-on and also set to 0 at an exit from power-off mode. When 1 is
written to the CWR bit by a program, it is set to 1. This bit remains unchanged at a hardware reset, software reset,
or watchdog timer reset.
The RSTFR register can be used to detect whether a hardware reset, software reset, or watchdog timer reset has
occurred.
If a hardware reset or an exit from power-off mode occurs, the HWR bit is set to 1 (detected).
If a software reset occurs, the SWR bit is set to 1 (detected).
If a watchdog timer reset occurs, the WDR bit is set to 1 (detected).
