Functions
Apply 5 V ± 10% to Vcc and 0 V to Vss.
Input
This pin controls the processor mode. Connect to Vss for the single-chip mode and the memory
expansion mode, and to Vcc for the microprocessor mode.
When “L” level is applied to this pin, the microcomputer enters the reset state.
These are pins of main-clock generating circuit. Connect a ceramic resonator or a quartz-
crystal oscillator between X
IN
and X
OUT
. When an external clock is used, the clock source should
be connected to the X
IN
pin, and the X
OUT
pin should be left open.
This pin functions as the enable signal output pin which indicates the access status in the internal
bus. In the memory expansion mode or the microprocessor mode, this pin functions as the RDE
signal output pin.
In the memory expansion mode or the microprocessor mode, this pin determines whether the
external data bus has an 8-bit width or a 16-bit width. The data bus has a 16-bit width when “L”
signal is input and an 8-bit width when “H” signal is input.
Power source input pin for the A-D converter. Externally connect AVcc to Vcc and AVss to Vss.

Input
This is reference voltage input pin for the A-D converter.

I/O
In the single-chip mode, port P0 becomes an 8-bit I/O port. An I/O direction register is available so
that each pin can be programmed for input or output. These ports are in the input mode when
reset.
In the memory expansion mode or the microprocessor mode, these pins output
0
–
4
signals, and address (A
16
, A
17
).
In the single-chip mode, these pins have the same functions as port P0. When the BYTE pin is set
to “L” in the memory expansion mode or the microprocessor mode and external data bus has a
16-bit width, high-order data (D
8
– D
15
) is input/output or an address (A
8
– A
15
) is output. When
the BYTE pin is “H” and an external data bus has an 8-bit width, only address (A
8
– A
15
) is output.
In the single-chip mode, these pins have the same functions as port P0. In the memory expansion
mode or the microprocessor mode, low-order data (D
0
– D
7
) is input/output or an address
(A
0
– A
7
) is output .
In the single-chip mode, these pins have the same function as port P0. In the memory expansion
mode or the microprocessor mode,
WEL
,
WEH
, ALE, and
HLDA
signals are output.
In the single-chip mode, these pins have the same functions as port P0. In the memory expansion
mode or the microprocessor mode, P4
0
, P4
1
, and P4
2
become
HOLD
and
RDY
input pins, and a
clock
φ
1
output pin, respectively. Functions of the other pins are the same as in the single-chip
mode. However, in the memory expansion mode, P4
2
can be selected as an
I/O port.
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for timers A0 to A3 and input pins for key input interrupt input (
KI
0
–
KI
3
).
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for timer A4, input pins for external interrupt input (
INT
0
–
INT
2
) and input pins
for timers B0 to B2. P6
7
also functions as a sub-clock
φ
SUB
output pin.
In addition to having the same functions as port P0 in the single-chip mode, these pins function as
input pins for A-D converter. P7
2
to P7
5
also function as I/O pins for UART2. Additionally, P7
6
and
P7
7
have the function as the output pin (X
COUT
) and the input pin (X
CIN
) of the sub-clock (32 kHz)
oscillation circuit, respectively. When P7
6
and P7
7
are used as the X
COUT
and X
CIN
pins, connect
a resonator or an oscillator between the both.
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for UART 0 and UART 1.
