The internal bus consists of CPU bus, memory bus, and peripheral bus. Bus Interface Unit (BIU) is used to
interfere with CPU, ROM/RAM, and perpheral functions by controling CPU bus, memory bus, and periph-
eral bus. Figure 6.3 shows the block diagram of the internal bus.
The number of bus cycle varies by the internal bus. Table 6.1 lists the accessible area and bus cycle.
