CENTRAL PROCESSING UNIT (CPU)

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.
ΠThe 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.
Ž 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 Œ to Ž, the BIU inputs and outputs bus control signals and controls the
buses.
Figure 2.2.1 shows the buses and bus interface unit (BIU).
