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.
Description
Reserved
These bits are always read as 0.
When the bit is set to 1, the corresponding pin is cut off
by PMOS and it functions as the NMOS open-drain
output. When cleared to 0, the pin functions as the CMOS
output.
Reserved
These bits are always read as 1.
