9.7
Port 8 is a general I/O port. Each pin of the port 8 is shown in figure 9.7.
Port 8 has the following registers.
9.7.1
PCR8 selects inputs/outputs in bit units for pins to be used as general I/O ports of port 8.
9.7.2
PDR8 is a general I/O port data register of port 8.

Port 8
Description
When each of the port 8 pins P87 to P85 functions as a
general I/O port, setting a PCR8 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
Reserved
Description
PDR8 stores output data for port 8 pins.
If PDR8 is read while PCR8 bits are set to 1, the value
stored in PDR8 is read. If PDR8 is read while PCR8 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR8.
Reserved
These bits are always read as 1.
