A
(Oscillator)
Crystal oscillator pins
83 to 90
85 to 92
D00 to D07
K
(TTL)
In non-multiplex mode, the I/O pins for the lower 8 bits of the
external data bus.
AD00 to AD07
In multiplexed mode, the I/O pins for the lower 8 bits of the
external address/data bus.
91 to 98
93 to 100 P10 to P17
K
(TTL)
General purpose I/O ports
This applies in non-multiplexed mode with an 8-bit external
data bus.
P08 to D15
In non-multiplexed mode, the I/O pins for the upper 8 bits of
the external data bus
This applies when using a 16-bit external data bus.
AD08 to AD15
In multiplexed mode, the I/O pins for the upper 8 bits of the
external address/data bus.

In non-multiplexed mode, the output pins for the lower 8 bits
of the external address bus.

B
(CMOS)
General purpose I/O ports
This applies in multiplexed mode.
A08 to A15
In non-multiplexed mode, the output pins for the upper 8 bits
of the external address bus.
16 to 20
22 to 24
18 to 22
24 to 26
P40 to P47
B
(CMOS)
General purpose I/O ports
This applies when the upper address control register
specifies port operation.
A16 to A23
The output pins for A16 to 23 of the external address bus
This applies when the upper address control register
specifies address operation.
25 to 28
27 to 30
P70 to P73
H
(CMOS/H)
General purpose I/O ports
This applies in all cases.
INT0 to INT3
External interrupt request input pins
As the inputs operate continuously when external interrupts
are enabled, output to the pins from other functions must be
stopped unless done intentionally.
