6-24 DSP Commands

Program 8-bit DMA mode digitized sound I/O

Output bCommand, bMode, wLength.LowByte, wLength.HighByte

Remarks Except for the high nibble being changed to 1100 binary, the bCommand byte is

organized identically as in command Bxh.

The bMode byte is organized exactly as in command Bxh.

For minimum signal amplitude, the signed 8-bit value is 00h; with unsigned data, the

equivalent value is 80h.

wLength is a word giving the number of 8-bit samples less 1.
