16.6.2 Reset Cause
When a Reset occurs, the bit corresponding to the Reset source is set to
‘1’ and all other bits are written to ‘0’.
If multiple Resets are requested at the same time, RCAUSE will indicate all of the requests that were active simultaneously, meaning that multiple flags may be set.
