Circuit

Function
A Crystal oscillator pins
B Operating mode selection pins
Connect directly to VCC or VSS .
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”.
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.
D General-purpose I/O ports
When an external bus is used, these ports function as
upper address output.
F General-purpose output-only port
When an external bus is used, this port can also be
used as a buffer control output by setting the BCTR.
F General-purpose output-only port
When an external bus is used, this port can also be
used as a hold acknowledge output by setting the
BCTR.
D General-purpose output-only port
When an external bus is used, this port can also be
used as a hold request input by setting the BCTR.
D General-purpose output-only port
When an external bus is used, this port functions as a
ready input.
F General-purpose output-only port
When an external bus is used, this port functions as a
clock output.
F General-purpose output-only port
When an external bus is used, this port functions as a
write signal output.
F General-purpose output-only port
When an external bus is used, this port functions as a
read signal output.
F General-purpose output-only port
When an external bus is used, this port functions as
an address latch signal output.
