Description
When the corresponding pin is designated in PMR1 as a
general I/O pin, setting a PCR1 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
Bit 3 is a reserved bit.
Description
PDR1 stores output data for port 1 pins.
If PDR1 is read while PCR1 bits are set to 1, the value
stored in PDR1 are read. If PDR1 is read while PCR1 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR1.
Bit 3 is a reserved bit. This bit is always read as 1.
