6.11 Over Voltage Protection
F81866A over voltage protection function could protect the damage from voltage spikes via over voltage
protection (OVP) function. Voltage protection function is enabled via setting the related register. When
the force mode occurs, the system would shut down and then can not boot at all. Only re-plugging the
power code (cut off VSB) could re-activate or re-boot the system at the force mode.
