PD78014 Subseries)
71
3.2.5 P40 to P47 (Port 4)
These are 8-bit input/output ports. Besides serving as input/output ports, they function as address/data bus.
Test input flag (KRIF) is set to 1 by falling edge detection.
The following operating modes can be specified in 8-bit units.
(1) Port mode
These ports function as 8-bit input/output ports. They can be specified in 8-bit units as input or output ports with
a memory expansion mode register (MM). When they are used as input ports, a pull-up resistor can be connected
to them with an on-chip pull-up resistor option register (PUO).
(2) Control mode
These ports function as low-order address/data bus pins in external memory expansion mode. When they are
used as address/data bus, an on-chip pull-up resistor is automatically unused.
3.2.6 P50 to P57 (Port 5)
These are 8-bit input/output ports. Besides serving as input/output ports, they function as address/data bus.
They can drive LEDs directly.
The following operating modes can be specified bit-wise.
(1) Port mode
These ports function as 8-bit input/output ports. They can be specified bit-wise as input or output ports with port
mode register 5 (PM5). When they are used as input ports, an on-chip pull-up resistor can be connected to them
with a pull-up resistor option register (PUO).
(2) Control mode
These ports function as high-order address bus pins in external memory expansion mode. When they are used
as address/data bus, the on-chip pull-up resistor is automatically disabled.
