This unit handles MIDI and audio capabilities. * The DSP can be reset, data/commands can be read or written to it, * and it can generate interrupts. Interrupts are generated for MIDI * input or DMA completion. They seem to have neglected the fact * that it would be nice to have a MIDI transmission complete interrupt. * Worse, the DMA engine is half-duplex. This means you need to do * (timed) programmed I/O to be able to record and play simulataneously. */ #define ESS_ACMD_DAC8WRITE 0x10 /* direct-mode 8-bit DAC write */ #define ESS_ACMD_DAC16WRITE 0x11
