Reset I/O pin
This pin is an N-ch open-drain output type with a pull-up
RST C resistor, and a hysteresis input type. "L" is output from this
pin by an internal reset reguest (optional).
The internal circuit is initialized by the input of "L".
General-purpose I/O ports
D When an external bus is used, these ports function as
multiplex pins of lower address output and data I/O.
General-purpose I/O ports
D When an external bus is used, these ports function as upper
address output.
General-purpose output-only port
F When an external bus is used, this port can also be used as
a buffer control output by setting the BCTR register.
General-purpose output-only port
F When an external bus is used, this port can also be used as
a hold acknowledge output by setting the BCTR register.
General-purpose output-only port
D When an external bus is used, this port can also be used as
a hold request input by setting the BCTR register.
General-purpose output-only port
When an external bus is used, this port functions as a ready
D
input. An external pull-up is required for this port if the ready
function is not used.
