16-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
BUS INTERFACE UNIT
Data transfer between the central processing unit (CPU) and inter-
nal memory, internal peripheral devices is always performed via the
bus interface unit (BIU), which is located between the CPU and the
internal buses.
Figure 5 shows the BIU and the bus structure. The CPU and BIU are
connected by a dedicated bus, and any transfer between the CPU
and BIU is controlled by this dedicated bus.
On the other hand, data transfer between the BIU and internal pe-

ripheral devices uses the following internal common buses: 32-bit
code bus, 16-bit data bus, 24-bit address bus, and control signals.
The bus control method where the code bus and the data bus sepa-
rate out (hereafter, this method is referred to as the separate code/
data bus method) is employed in order to improve data transfer ca-
pabilities. As a result, the internal memory is connected to both the
code bus and the data bus, and registers of all other internal periph-
eral devices are connected only to the data bus.
