Definitions of Variables:
Each bit in the lower nibble of each Register represents the setting of a GPIO port.
Super IO Pin Pin Name Bit GPIO DIO
111 GPIO80 0 GPIO DIO-In0
112 GPIO81 1 GPIO DIO-In1
113 GPIO82 2 GPIO DIO-In2
114 GPIO83 3 GPIO DIO-In3
115 GPIO84 4 GPIO DIO-Out0
116 GPIO85 5 GPIO DIO-Out1
117 GPIO86 6 GPIO DIO-Out2
118 GPIO87 7 GPIO DIO-Out3
Value of Output Data / Input Data :
If a port is assigned to be an output port, then its respective bit can be
read/written.
If a port is assigned to be an input port, then its respective bit can be read only.
Note:
DIO-IN0/DIO-IN1/DIO-IN2/DIO-IN3 are programmed as
Inputs
by BIOS default.
Parameter Conditions
VinH min +1.857V
VinL max +0.525V
Rated Vin -8V ~ +12V
NC Status High by Default
** Attention: If
DIO-IN0/DIO-IN1/DIO-IN2/DIO-IN3
are programmed as Output signal, they
can only offer a normal signal transfer.(NOT amplified signals.)
Parameter Conditions
VoutH 3.3V thru 10k
VoutL 0V thru 1k
DIO-OUT0/DIO-OUT1/DIO-OUT2/DIO-OUT3 are fixed as
Outputs
by BIOS.
Parameter Conditions
Open-drain buffer Power-on default = Open
Driving Capacity max 100mA continue
