The user can simulate an external reset (XRS) in software. This can be done by setting the XRSn bit to 1 in the SIMRESET register by software. This toggles the XRS pin and resets the full device (just like external reset).
After this reset, the SIMRESET_XRSn and XRSn bits in the RESC register are set. Software can read these bits to know the cause of the reset and clear the status by writing a 1 into the corresponding bits in the RESCCLR register.
