6-3-3 Waveform Description
When micom accesses each device sharing bus, it falls the chip select signal of corresponding chip to (CS2:MIC8-22,
/DSPCS:DIC1-2, /DVDCS:VIC1-206/SRVCS:SIC1-10) 0 (Low) before trial.
So to speak, the bus is used by time-division as shown in Fig 6-14, 6-15, 6-16.
Two and more devices can't be accessed simultaneously.
• CH1 : CS2 (MIC8-22, EPROM CHIP SELECT)
• CH2 : DSPCS (DIC1-2, DATA PROCESSOR CHIP SELECT)
• CH3 : DVDCS (VIC1-206, A/V DECODER CHIP SELECT)
• CH4 : SRVCS (SIC1-10, DIGITAL SERVO CHIP SELECT)
• CH5 : WR (MIC1-73, MICOM OUTPUT WRITE SIGNAL)
• CH6 : RD (MIC1-72, MICOM OUTPUT READ SIGNAL)
