These are 8-bit I/O ports. Besides serving as I/O ports, they function as an address/data bus.
The interrupt request flag (KRIF) can be set to 1 by detecting a falling edge.
The following operating mode can be specified in 1-bit units.
Caution
These are 8-bit I/O ports. Besides serving as I/O ports, they function as an address bus.
Port 5 can drive LEDs directly.
The following operating modes can be specified in 1-bit units.
These are 4-bit I/O ports. Besides serving as I/O ports, they are used for control in external memory expansion
The following operating modes can be specified in 1-bit units.
These ports function as 8-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode
register 4 (PM4). On-chip pull-up resistors can be used by setting pull-up resistor option register 4 (PU4).
These ports function as lower address/data bus pins (AD0 to AD7) in external memory expansion mode.
These ports function as 8-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode
register 5 (PM5). On-chip pull-up resistors can be used by setting pull-up resistor option register 5 (PU5).
These ports function as higher address bus pins (A8 to A15) in external memory expansion mode.
These ports function as 4-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode
register 6 (PM6).
On-chip pull-up resistors can be used by setting pull-up resistor option register 6 (PU6).
These ports function as control signal output pins (RD, WR, WAIT, ASTB) in external memory expansion mode.
Caution
mode register (MEM) to 01H.
When using the falling edge detection interrupt (INTKR), be sure to set the memory expansion
When external wait is not used in external memory expansion mode, P66 can be used as an
I/O port.
