Digitized Sound I/O Programming 3-9
The tables below list the sampling ranges for the supported DMA modes among the
various DSP versions. Normal on the "Transfer Mode" column refers to non high-
speed DMA mode. You must take note of the information below when programming
for the different versions of the DSP.
