Host Master/ATAPI Interface

This 16 bits parallel host interface allows the
CS98000 to be a host master, controlling other de-
vices that would be used on the same system. The
interface supports a programmable protocols and
speeds, including multiplexed and non-multiplexed
addressing. Slaves with different protocols can be
connected at the same time, controlled by different
chip selects.

6.10

DVD I/O Channel Interface

This interface connects to standard DVD loaders,
and consists of three parts: Control, DVD Data and
CD Data. This interface shares CS98000 pins with
the Host Master/ATAPI interface. The definition of
the pins is set via register programming, and the
two modes are mutually exclusive.

6.11

General Purpose Input/Output
(GPIO)

The CS98000 provides 37 GPIO pins, each with in-
dividual output tri-state controls. Additional pins
may also be re-defined and GPIO’s.

6.12

Power and Ground

The CS98000 requires 3 different types of power
supplies – PLLs, internal logic and IO pins -. The
PLLs and internal logic use 2.5 V power supply,
The IO pins use 3.3 V power supply, and are 5 V
input tolerant.
