This pin is a power supply input for the A-D converter. Connect this
pin to V

This is an 8-bit I/O port equivalent to P0. Pins in this port also function
as external interrupt pins as selected by software.
These pins output 8 low-order address bits (A

This is an 8-bit I/O port equivalent to P0.
This pin switches between processor modes. Connect this pin to the
V
mode (memory expansion mode) or the V
operation in microprocessor mode.
A “L” on this input resets the microcomputer.
These pins are provided for the main clock generating circuit.Connect

X
This pin selects the width of an external data bus. A 16-bit width is
selected when this input is “L”; an 8-bit width is selected when this
input is “H”. This input must be fixed to either “H” or “L”. Connect this
pin to the V
This pin is a power supply input for the A-D converter. Connect this
pin to V
This pin is a reference voltage input for the A-D converter.
This is an 8-bit CMOS I/O port. It has an input/output port direction
register that allows the user to set each pin for input or output
individually. When used for input in single-chip mode, the port can be
set to have or not have a pull-up resistor in units of four bits by
software. In memory expansion and microprocessor modes, selection
of the internal pull-resistor is not available.
When set as a separate bus, these pins input and output data
This is an 8-bit I/O port equivalent to P0.
