|
These are the I/O port mapping offsets and bit assignments used
|
|
by Creative Labs in their implementation of the host interface for
|
|
the Matsushita CD-ROM drive. These may be different in the adapter
|
|
cards (including sound cards) made by other vendors.
|
|
It is unknown if the Creative interface is based on a reference design
|
|
provided by Matsushita (other interface vendors would similar or
|
|
identical if this was the case).
|
|
|
|
The drive is actually capable of some things that the Creative
|
|
interface doesn't implement, such as DMA and interrupts.
|
|
|
|
See matcd.h for defines related to the Matsushita drive itself.
