6-6 DSP Commands
The following discusses the DSP commands in ascending order:
10h
Output
10h, bData
Remarks
Output one byte unsigned digitized sound data to the DSP. The application is
responsible for controlling the sampling rate.
The proper transfer sequence is:
1. Send command 10h.
2. Send a byte of digitized sound data.
3. Wait for the correct timing and repeat steps 1 and 2 until all digitized sound data
has been sent.
See Also command 20h, 8-bit direct mode single byte digitized sound input
Available 1.xx
14h
Output
14h, wLength.LowByte, wLength.HighByte
Remarks
Output unsigned digitized sound data using Single-cycle DMA mode. wLength is a
word giving the number of 8-bit samples less 1.
