Function
A
Crystal oscillator pins
(Oscillator)
K
In non-multiplex mode, the I/O pins for the lower 8 bits of the
(TTL) external data bus.
In multiplexed mode, the I/O pins for the lower 8 bits of the
external address/data bus.
K
(TTL)
General purpose I/O ports
This applies in non-multiplexed mode with an 8-bit external
data bus.
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.
In multiplexed mode, the I/O pins for the upper 8 bits of the
external address/data bus.
B
General purpose I/O ports
(CMOS) This applies in multiplexed mode.
In non-multiplexed mode, the output pins for the lower 8 bits
of the external address bus.
B
General purpose I/O ports
(CMOS) This applies in multiplexed mode.
In non-multiplexed mode, the output pins for the upper 8 bits
of the external address bus.
B
General purpose I/O ports
(CMOS) This applies when the upper address control register
specifies port operation.
The output pins for A16 to 23 of the external address bus
This applies when the upper address control register
specifies address operation.
H
General purpose I/O ports
(CMOS/H) This applies in all cases.
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.
