10.3.2 Reset Status Register (RSR)
The 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 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.
