Setting to one will enable the corresponding OVT1# output. Clearing to 0 will disable that OVT1# output.
The OVT1# function is enabled or disabled by the EN_OVT1 control bit at CR58.Bit0.
The OVT1# signal will be issued when the selected temperature channel detects the temperature
exceeds the allowed range 4 times in a row.

exceeds Tcritical (Critical Temperature), the OVT# pin will be de-asserted. If the
temperature falls below T
by reading temperature sensors (interrupt status). Once the interrupt is generated, the
OVT# pin does not issue additional interrupts even it the temperature remains above
Tcritical.
