Function
Supply 4.2 V to 5.5 V to the VCC pin. Supply 0 V to the VSS pin.
This pin switches between processor modes. Connect it to the VSS
pin when operating in single-chip or memory expansion mode.
Connect it to the VCC pin when operating in microprocessor mode.
A “L” on this input resets the microcomputer.
These pins are provided for the main clock generating circuit.
Connect a ceramic resonator or crystal between the XIN and the
XOUT pins. To use an externally derived clock, input it to the XIN pin
and leave the XOUT pin open.
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”. When
operating in single-chip mode, connect this pin to VSS. In M30623
(80-pin package), the BYTE signal is internally connected to the
CNVSS signal.
This pin is a power supply input for the A-D converter. Connect this
pin to VCC.
This pin is a power supply input for the A-D converter. Connect this
pin to VSS.
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. Pins in this port
also function as A-D converter extended input pins as selected by
software when operating in single-chip mode.
When set as a separate bus, these pins input and output data (D0–D7).
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.
When set as a separate bus, these pins input and output data (D8–D15).
This is an 8-bit I/O port equivalent to P0. Pins in this port also
function as A-D converter extended input pins as selected by
software when operating in single-chip mode.
These pins output 8 low-order address bits (A0–A7).
If the external bus is set as an 8-bit wide multiplexed bus, these pins
input and output data (D0–D7) and output 8 low-order address bits
(A0–A7) separated in time by multiplexing.
If the external bus is set as a 16-bit wide multiplexed bus, these pins
input and output data (D0–D6) and output address (A1–A7)
separated in time by multiplexing. They also output address (A0).
This is an 8-bit I/O port equivalent to P0.
These pins output 8 middle-order address bits (A8–A15).
If the external bus is set as a 16-bit wide multiplexed bus, these pins
input and output data (D7) and output address (A8) separated in time
by multiplexing. They also output address (A9–A15).
