2.2 Bus interface unit
The microcomputer has a bus interface unit (BIU) between the central processing unit (CPU) and
memory I/O unit. The BIU’s function and operation are described below. When connecting external devices,
refer to chapter “12. CONNECTING EXTERNAL DEVICES,” also.
2.2.1 Overview
Transfer operation between the CPU and memory I/O unit is always performed via the BIU.
The BIU reads an instruction from the memory before the CPU executes it.
When the CPU reads data from the memory /O unit, the CPU informs the BIU of the address where
the data resides. The BIU reads the data from the address and pass it to the CPU.
When the CPU writes data to the memory I/O unit, the CPU informs the BIU of the address where the
data resides. The BIU writes the data to the address.
In order to realize operations to , the BIU inputs and outputs bus control signals and controls the
buses.
Figure 2.2.1 shows the buses and bus interface unit (BIU).
