Dio Interface Introduction; Dio Connector Pinouts - IEI Technology NOVA-9102 User Manual

NOVA-9152 and NOVA-9102 5.25" Motherboard
D.1 DIO Interface Introduction
The DIO connector on the NOVA-9152 and NOVA-9102 is interfaced to the LC4032/64-T8
chipset. The DIO has both 12-bit digital inputs and 12-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 Winbond
Super I/O chipset.
