Description
Reserved
When each of the port 2 pins P22 to P20 functions as an
general I/O port, setting a PCR2 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
Description
Reserved
These bits are always read as 1.
PDR2 stores output data for port 2 pins.
If PDR2 is read while PCR2 bits are set to 1, the value
stored in PDR2 is read. If PDR2 is read while PCR2 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR2.
