W83791D
Preliminary
At this mode, temperature exceeding one level of temperature separation, starting from 0 degree, causes the
OVT# output activated. OVT# will be activated again once temperature exceeds the next level. OVT# output will
act the same manner when temperature goes down. (Figure 13-1).
The granularity of temperature separation between each OVT# output signal can be programmed at Bank0 CR[4Ch]
bit 4-5.
