Description
When each of the port 5 pins P57 to P50 functions as a
general I/O port, setting a PCR5 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
Note: The PCR57 and PCR56 bits should not be set to 1
Description
Stores output data for port 5 pins.
If PDR5 is read while PCR5 bits are set to 1, the value
stored in PDR5 are read. If PDR5 is read while PCR5 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR5.
Note: The P57 and P56 bits should not be set to 1 in the
in the H8/3687N.
H8/3687N.
