X0
A
Crystal oscillator pins (10 MHz)
14
X1
11
MOD0
B
Operating mode selection pins
Connect directly to VCC or VSS.
12
MOD1
16
RST
C
Reset I/O pin
This pin is an N-ch open-drain output type with a pull-up resistor,
and a hysteresis input type. “L” is output from this pin by an
internal reset source. The internal circuit is initialized by the input
of “L”.
40 to 33
P00 /AD0 to
P07/AD7
D
General-purpose I/O ports
When an external bus is used, these ports function as multiplex
pins of lower address output and data I/O.
32 to 25
P10 /A08 to
P17/A15
D
General-purpose I/O ports
When an external bus is used, these ports function as upper
address output.
24
P20/BUFC
F
General-purpose output port
When an external bus is used, this port can also be used as a
buffer control output.
23
P21/HAK
F
General-purpose output port
When an external bus is used, this port can also be used as a hold
acknowledge output.
22
P22/HRQ
D
General-purpose output port
When an external bus is used, this port can also be used as a
hold request input.
21
P23/RDY
D
General-purpose output port
When an external bus is used, this port functions as a ready
input.
20
P24/CLK
F
General-purpose output port
When an external bus is used, this port functions as a clock
output.
19
P25/WR
F
General-purpose output port
When an external bus is used, this port functions as a write
signal output.
18
P26/RD
F
General-purpose output port
When an external bus is used, this port functions as a read signal
output.
17
P27/ALE
F
General-purpose output port
When an external bus is used, this port functions as an address
latch signal output.
48
P30/SCK1
E
General-purpose I/O port
Also serves as the clock I/O for the UART.
This port is a hysteresis input type.
