C.1 DIO Interface Introduction
The DIO connector on the WAFER-945GSE is interfaced to GPIO ports on the ITE
IT8718F Super I/O chipset. The DIO has both 4-bit digital inputs and 4-bit digital outputs.
The digital inputs and digital outputs are generally control signals that control the on/off
circuit of external devices or TTL devices. Data can be read or written to the selected
address to enable the DIO functions.
NOTE:
For further information, please refer to the datasheet for the ITE
IT8718F Super I/O chipset.
C.2 DIO Connector Pinouts
The following table describes how the DIO connector pins are connected to the Super I/O
GPIO port.
