C.1 Introduction
The DIO connector on the NANO-9452 is interfaced to GPIO ports on the 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 IT8712F
Super I/O chipset.
