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 CPU1 software. This toggles the XRS pin; hence, resetting the full device (just like an external reset).
After this reset, the SIMRESET_XRSn bit in the RESC register is set. Software can read this bit to know the cause of the reset and clear the status by writing a 1 into the corresponding bit in the RESCCLR register.
