Read/Write Logic 1 enables start-up of
monitor ASIC, Logic 0 places
the ASIC in standby mode. At
start-up, limit checking func-
tions and scanning begins. Note,
all HIGH and LOW LIMITS
should be set into the ADM1025/
ADM1025A prior to turning on
this bit. (Power-up Default = 0)

Read/Write Setting this bit generates a
minimum 20 ms low pulse on
Pin 16, if the function is
enabled.
Read/Write Selects whether Pin 11 acts
as a 12 V Analog Input monitor-
ing pin, or as a VID[4] input.
This pin defaults to the 12 V
Analog Input. (Default = 0)
Read
Initialization Read/Write Logic 1 restores power-up
default values to the Configu-
ration Register and Status
Registers. This bit automati-
cally clears itself and the power-
on default is zero.

Test Register = 1, and Bit 7
of VID Register = 0, then
setting this bit to 1 config-
