C.1 DIO Interface Introduction
The DIO connector on the IMBA-9654 is interfaced to GIO ports on the iTE 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 Super
I/O chipset.
