System Data Bus. data lines must stable when active during write before DTACK asserted during read. Tri-state. Chip Select. Used access CIAP internal registers buffers. Active LOW. Read/Write. Indicates direction data transfer. When LOW, transfer CIAP. Data Transfer Acknowledge. Active LOW. During normal host access, DTACK output indicating that data been (read cycles) read from (write cycles) data bus. (Active pullup.) During DMA, DTACK input indicating that memory data data bus. Interrupt. Released when interrupt status register read. Active LOW. Interrupt Acknowledge. Active LOW. Request. Active LOW. Acknowledge. handshake signal indicating that available data transfer. Active LOW. Ready. handshake signal indicating that CIAP completed data transfer. Tri-state. Active LOW. When released CIAP, output forced high nanoseconds before made tri-state. Done.

MCD221 Data Flow Diagram should used conjunction with following notes which outline function various blocks within device: data input module consists parts; main channel decoder subchannel decoder. Both decoders active same time. main channel decoder different modes; CD-DA mode, CD-ROM mode, CD-i mode.
audio processor module accepts external audio input and, after processing, generates audio output. microcode controller interface takes care accepting commands passing data different parts audio processing unit. host interface takes care addressing internal registers buffers. CIAP interface with possible hosts; 68000 type host microcontroller that interfaces serial link.
