Logic 1 enables startup of monitor device, logic 0 places the device in standby mode.
Power–up default = 0.
At startup, limit checking functions and scanning begins. Note, all High and Low limits
should be set into the ASIC prior turning on this bit.
Power-up default = 0.
Power-up default = 0.
Power-up default = 1.
Setting this bit generates a minimum 20ms low pulse on the Reset pin, if the reset
function is enabled. Power-up default = 0.
Selects whether pin 11 acts as a 12 volt analog input monitoring pin, or as a VID[4] input.
This pin defaults to the 12 volt analog input. Power–up default = 0.
Power–up default = 0.
Logic 1 restores power–up default values to the configuration register and the status
registers. This bit automatically clears itself. Power–up default = 0.

The VID[0:3] inputs from Pentium/PRO power supplies ID to indicate the operating
voltage (e.g. 1.5V to 2.9V). Power-up default = VID[0:3].
Undefined.
When set to 1, enables the RESET pin output function.
This bit defaults to 0 at Power–up and enables addressing function.
VID4 input, if selected, from Pentium/PRO power supplied ID.
Power-up default = 0 and pin 11 is not selected for VID4.
Power-up default = 1000 000
