VID0/GPIO1/TACH1
VID0: Digital Input (Open Drain). Voltage supply readouts from CPU. This value
is read in to the VID value register (0x97).
TACH1
GPIO1: Open-Drain I/O. General-purpose input/output.
TACH1: Digital Input (Open Drain). Fan tachometer input to measure speed of
Fan 1.
2
VID1/GPIO2/TACH2
VID1: Digital Input (Open Drain). Voltage supply readouts from CPU. This value
is read in to the VID value register (0x97).
TACH2
GPIO2: Open-Drain I/O. General-purpose input/output.
TACH2: Digital Input (Open Drain). Fan tachometer input to measure speed of
Fan 2.
3
VID2/GPIO3/TACH3
VID2: Digital Input (Open Drain). Voltage supply readouts from CPU. This value
is read in to the VID value register (0x97).
TACH3
GPIO3: Open-Drain I/O. General-purpose input/output.
TACH3: Digital Input (Open Drain). Fan tachometer input to measure speed of
Fan 3.
4
VID3/GPIO4/TACH4
VID3: Digital Input (Open Drain). Voltage supply readouts from CPU. This value
is read in to the VID value register (0x97).
TACH4
GPIO4: Open-Drain I/O. General-purpose input/output.
TACH4: Digital Input (Open Drain). Fan tachometer input to measure speed of
Fan 4.
5
VCC
