19. VID INPUTS AND OUTPUTS
The W83627DHG-P provides eight pins for VID input or output function. The default function is VID
input. These pins can be configured to VID output function by setting Logical Device B, CR [F0h], bit 7
to 0. The configuration is applied to the 8 pins as a group. None of them can be individually set to
input or output.
The W83627DHG-P supports Intel VRM 9/10/11 and AMD VRM VID detections. H/W strapping and
S/W programming can set the following three input levels. a) and b) can be set by H/W strapping or
S/W programming, while c) can only be set by S/W programming.
a) TTL (Vih = 2 V; Vil = 0.8V) –
b) GTL (Vih = 0.6 V; Vil = 0.4 V) – (Default)
c) AMD VRM (Vih = 1.4V; Vil = 0.8V) –
The input data can be read in the data register at Logical Device B, CR [F1h], bit 7 ~ 0. It is a
read/write register where bit 7~0 corresponds to VID pin 7~0. Please note that in the input mode,
writes to this register have no effect.
The output type of the eight VID pins is push-pull, and they drive to 3VCC (3.3V) when configured to
the output mode. The output data can be set in the data register (Logical Device B, CR [F1h], bit 7 ~
0). The written data can be read if Configuration Register CR [2Ch], bit 3 is set to “0”.
1) Add a pulled-down resistor at Pin 77(EN_GTL), or
2) Set Configuration Register CR [2Ch], bit 3 to “0”;
1) No extra pulled-up resistor needed, or
2) Set Configuration Register CR [2Ch], bit 3 to “1”;
19.1 VID Input Detection
19.2 VID Output Control
Set Configuration Register CR [2Ch], bit 3 to “1” and Logical Device B, CR [F0h], bit 6 to “1”.
