Description
When each of the port 8 pins P87 to P80 functions as
an 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.
Description
PDR8 stores output data for port 8 pins.
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.
