2-2. Sound Blaster Pro Block
This block emulates the DSP commands of Sound Blaster and Sound Blaster Pro.
Only playback
functions are supported (record functions are not supported).
However, to maintain compatibility for
games, it is designed so that every DSP command receives a correct response.
The DMA transfer of this block uses PC/PCI or D-DMA protocol.
The following shows the SBBase I/O map of SB Pro.
