DRPC-100 Embedded System
C.1 Introduction
The DIO connector on the DRPC-100 is interfaced to GPIO ports on the 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 Super I/O
chipset.
