6-6 DSP Commands
The following discusses the DSP commands in ascending order:
10h
8-bit direct mode single byte digitized sound
output
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.

14h
8-bit single-cycle DMA mode digitized sound
output
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.
