detected.
PORSF: Power-On Reset Force and Flag.
This bit is set anytime a power-on reset occurs. Writing this bit enables/disables the V
monitor (VDDMON0) as a reset source. Note: writing 1 to this bit before the V
tor is enabled and stabilized may cause a system reset. See register VDDMON (SFR
Definition 11.1)
