This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
6.3.7. IDE / ISA DYNAMIC DEMULTIPLEXING
Some of the ISA bus signals are dynamically
multiplexed to optimize the pin count. Figure 6-12
describes how to implement the external glue
logic to demultiplex the IDE and ISA interfaces. In
Local Bus mode the two buffers are not needed
and the NAND gates can be simplified to inverters.
6.3.8. BASIC AUDIO USING IDE INTERFACE
When the application requires only basic audio
capabilities, an audio DAC on the IDE interface
can avoid using a PCI-based audio device. This
low cost solution is not CPU consuming thanks to
the DMA controller implemented in the IDE
controller and can generate 16-bit stereo sound.
The clock speed is programmable when using the
speaker output.
