C.1 DIO Interface Introduction
The DIO connector on the IMB-Q354 is interfaced to GPIO ports on the ITE IT8712F
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
IT8712F Super I/O chipset.
C.2 DIO Connector Pinouts
