Description
VID4 Input (If Selected)
(Defaults to 0)
Description
The VID[3:0] inputs from
Pentium/PRO power
supplies to indicate the
operating voltage (e.g.,
1.3 V to 2.9 V).
Undefined
Configures offset register
to be used with internal
or external channel. If Bit
0 of Test Register = 1 and
Bit 7 of VID Register = 0,
then setting this bit to 1
configures tHhe Offset
Register to the internal
temperature channel.
Clearing this bit
configures the Offset
Register to the external
temperature channel.
(Default = 0.)
When set to 1, enables
the RST output function
on Pin 16. This bit
defaults to 0 on power-
up. ( RST Disabled.)
