Write:
The reset status register (RSR) contains a status bit for every reset
source. When reset is entered, the cause of the reset condition is latched
along with a value of 0 for the other reset sources that were not pending
at the time of the reset condition. These values are then reflected in the
RSR. One or more status bits may be set at the same time. The cause
of any subsequent reset is also recorded in the register, overwriting
status from the previous reset condition.
RSR can be read at any time. Writing to RSR has no effect.
SOFT— Software Reset Flag
WDR — Watchdog Timer Reset Flag
POR — Power-On Reset Flag
SOFT indicates that the last reset was caused by software.
WDR indicates that the last reset was caused by a watchdog timer
timeout.
POR indicates that the last reset was caused by a power-on reset.
