SOFTRST — Software Reset Request Bit
The SOFTRST bit allows software to request a reset. Note that the
reset caused by setting this bit clears this bit.
1 = Request software reset
0 = No software reset request
FRCRSTOUT — Force RSTOUT Pin Bit
The FRCRSTOUT bit allows software to assert or negate the external
RSTOUT pin.
1 = Assert the RSTOUT pin.
0 = Do not assert the RSTOUT pin.
CAUTION:
External logic driving reset configuration data during reset needs to be
considered when asserting the RSTOUT pin when setting
FRCRSTOUT.
