OVT# Mode Select. There are two OVT# signal output
type.
<0> - Comparator Mode: (Default)
Temperature exceeding T_O causes the OVT# output
activated until the temperature is less than T_HYST.
<1> - Interrupt Mode:
Setting temperature exceeding T_O causes the OVT#
output activated indefinitely until reset reading
temperature sensor 1/2 registers. Temperature exceeding
T_O, then OVT# reset, and then temperature going below
T_HYST will also cause the OVT# activated indefinitely until
reset by reading temperature sensor 1/2. Once the OVT#
will not be activated by exceeding T_O, then reset, if the
temperature remains above T_HYST, the OVT# will not be
active again.
