(3) Waveform Description
When micom accesses each device sharing bus, it falls the chip select signal of corresponding chip to
(/dspcs : ZIC1-123, /FLASH DSP : ZIC1-126, /DSPCS : DIC1-2, /DVD1CS : ZIC1-208, CSB : SIC1-10)
0 (Low) before trial.
So to speak, the bus is used by time-division as shown in Fig. 7-41.
Two and more devices can't be accessed simultaneously.
