Preliminary Technical Data
Description
Logic 1 enables startup of
monitor ASIC, and Logic 0
places the ASIC in standby
mode. At startup, limit
checking functions 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.)
Setting this bit generates a
minimum 20 ms low pulse on
Pin 16 if the function is
enabled.
Selects whether Pin 11 acts
as a 12 V analog input
monitoring pin, or as a VID[4]
input. This pin defaults to the
12 V analog input. (Default =
0.)
Logic 1 restores power-up
default values to the
Configuration Register and
Status Registers. This bit
automatically clears itself and
the power-on default is zero.
