BIT 7
High Byte Access of Winbond Vendor ID. Set to 1, read 4Fh will
get 5Ch ; Clear as 0, read 4Fh will return A3h.
Bank select is to change current indexed bank. Available banks
are 0,1, and
Set this bit enables VID with 0.8/0.4V level. Clear this bit makes
VID in input mode with TTL level. Default value is set by VRM10
power-on trapping.
Set this bit enables FAN6 Functionality. Default is Watch Dog
Timer Function.
Clear this bit to 0 will perform Watch Dog Functionality on Pin
47/48.
Set to enable VIDA with offset output at VID port B.
Clear to disable this function.
Set to enable VIDB with offset output at VID port A.
Clear to disable this function.
reserved
Set to enable FAN7 function and disable Thermaltrip/VRM_EN
pin function.
Thermal Trip Level Selector. These two bits select the input level
for ThermalTrip 1/2. 11b is 1.0Vref GTLP. 10b enables 0.8Vref
GTL. 00b set these 2 pins to TTL.
