Register 16: Reset Cause (RESC), offset 0x05C
This field specifies the cause of the reset event to software. The reset value is determined by the
cause of the reset. When an external reset is the cause (EXT is set), all other reset bits are
cleared. However, if the reset is due to any other cause, the remaining bits are sticky, allowing
software to see all causes.
