Contains upper limit settings for MON3. If the
limit is violated, a flag in Main Device byte 71h
is set.
Contains lower limit settings for MON3. If the
limit is violated, a flag in Main Device byte 71h
is set.
Digitized measured value for temperature.
See Table 1.
Digitized measured value for V
See Table 1.
Digitized measured value for MON1.
See Table 1.
Digitized measured value for MON2.
See Table 1.
Digitized measured value for MON3.

Resistor status bit. A high indicates that both
resistors are in high-impedance mode. A low
indicates that both resistors are operating
normally.
Resistor control bit. Setting this bit high
causes both resistors to go into a high-
impedance state.
This status bit is high when OUT1 is high
assuming there is an external pullup resistor
on OUT1.
This status bit is high when OUT2 is high
assuming there is an external pullup resistor
on OUT2.
This status bit goes high when V
below the POA level.
