Signals, required to access external devices, are provided and software wait states are inserted as follows.
The signals are available in memory expansion mode and microprocessor mode only.

Address bus is a signal accessing 16-Mbyte space and uses 24 control pins; A
inversed output signal of the highest-order address bit.
Data bus is a signal for data input and output. The DS register selects an 8-bit data bus from D
a 16-bit data bus from D
BYTE pin, the data bus accessing the external memory space 3 becomes an 8-bit data bus after reset.
When applying a low-level ("L") signal to the BYTE pin, the data bus accessing the external memory
space 3 becomes the 16-bit data bus.
When changing single-chip mode to memory expansion mode, the address bus is in an indeterminate
state until the microcomputer accesses an external memory space.
Chip-select signal shares pins with A
determine which CS area is accessed and how many chip-select signals are output. A maximum of four
chip-select signals can be output.
In microprocessor mode, no chip-select signal, aside from A
is output after reset.
The chip-select signal becomes "L" while the microcomputer is accessing the external CSi area (i=0 to 3).
It becomes "H" while the microcomputer is accessing other external memory space.
Figure 8.2 shows an example of the address bus and chip-select signal output.
