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”.
General-purpose I/O ports
When an external bus is used, these ports
function as the multiplex pins of the lower address
output and the data I/O.
General-purpose I/O ports
When an external bus is used, these ports
function as an upper address output.
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.
General-purpose output-only port
When an external bus is used, this port can also
be used as a hold acknowledge by setting the
BCTR.
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.
General-purpose output-only port
When an external bus is used, this port functions
as a ready input.
General-purpose output-only port
When an external bus is used, this port functions
as a clock output.
General-purpose output-only port
When an external bus is used, this port functions
as a write signal output.
General-purpose output-only port
When an external bus is used, this port functions
as a read signal output.
