The W83795G/ADG provides VSEN1, VSEN2 and VSEN3 monitoring channels. VSEN1, VSEN2 and
VSEN3 Channels are automatically monitored once 3VSB is applied onto the W83795G/ADG, but the
W83795G/ADG will issue alert information only when the corresponding high/low limits of VSEN1,
VSEN2 and VSEN3 channels are being violated. ASF is also based on these limit registers to judge the
current channel status and report to the host.
Two methods are used to assign the VSEN1, VSEN2 and VSEN3 Limits, manually or automatically by
VID inputs. The following register sets allow users to choose their preferred method.
The W83795G/ADG supplies one set of VID input pins for VSEN1, VSEN2 and VSEN3 channels. If
dynamic VID function is enabled, the high/low limit of VSEN1, VSEN2 and VSEN3 channel will
auto-update when the VID input value changes.
Some VID input pins are multi-function pin. Programming Multi-Function Pin Control Registers properly
is required to make these pins function.
VID function is not for W83795ADG, they are reserved registers.

If write 1, enable dynamic VID function for VSEN3
If VID is changed, the high/low limit of corresponding VSEN3 sensing voltage will be
auto-updated. If manually programming High/Low limit of VSEN3 sensing voltage is
required, this bit has to be cleared as 0.
EN_DVID2.
If write 1, enable dynamic VID function for VSEN2
If VID is changed, the high/low limit of corresponding VSEN2 sensing voltage will be
auto-updated. If manually programming High/Low limit of VSEN2 sensing voltage is
required, this bit has to be cleared as 0.
EN_DVID1.
If write 1, enable dynamic VID function for VSEN1
If VID is changed, the high/low limit of corresponding VSEN1 sensing voltage will be
auto-updated. If manually programming High/Low limit of VSEN1 sensing voltage is
required, this bit has to be cleared as 0.
If write 1 (write clear),
