In some cases, the user can need to simulate the external reset (XRS) in software. This can be done using software by setting XRSn bit to 1 in SIMRESET register. This toggles the XRS pin and resets the full device (just like an 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 reset and clear the status by writing a 1 into corresponding bits in RESCCLR register.
