Description
8-bit I/O ports in CMOS, having a direction register to select an
input or output. Each pin is set as an input port or output port. An
input port in single-chip mode can be set for a pull-up or for no
pull-up in 4-bit unit by program. When these pins are used as bus
control signals in memory expansion mode and microprocessor
mode, internal pull-up resistance cannot be selected. Ports used
as input ports can be set for a pull-up or for no pull-up in these
modes above.
Input and output data (D0 to D7) when setting these pins as
data bus.
8-bit I/O ports equivalent to P0
Output 8 low-order address bits (A0 to A7).
Input and output data (D0 to D7) and output 8 low-order address
bits (A0 to A7) by time-sharing when setting these pins as
multiplex bus.
Input and output data (D8 to D15) and output 8 middle-order
address bits (A8 to A8) by time-sharing when setting an external
16-bit data bus as multiplex bus.

Connect VCC pin to 3.0 to 5.5 V.
Connect VSS pin to 0 V.
Switches processor mode. Connect this pin to VSS to start up in
single-chip the (memory expansion mode). Connect this pin to
VCC to start up in microprocessor mode.
The microcomputer remains in a reset state when setting the pin to "L".
I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN pin and XOUT pin. To
use an externally generated clock, input a clock from XIN pin to
leave XOUT pin open.
Switches a data bus in external memory space 3. Data bus in 16
bits long when setting this pin to "L" and 8 bits long when settig
this pin to "H". Set it to either one. Connet this pin to VSS when
an external bus is not used.
Inputs the power supply for A-D converter and D-A converter.
Connect this pin to VCC.
Inputs reference voltage for A-D converter.

8-bit I/O ports equivalent to P0
Analog input pins for A-D converter.
I/O ports equivalent to P0
Output 8 middle-order address bits (A8 to A15).
8-bit I/O ports equivalent to P0
Output 8 high-order address bits (A16 to A22, A23).
The uppermost bit (A23) inversed is also output.
Output CS0 to CS3 signals. CS0 to CS3 are chip-select signals
to specifly access space.
Output row addresses and column addresses by time-sharing
when accessing the DRAM space.
