R/W These bits store output data of a pin which is used
R/W ^{as a general output port. When the pin functions}
as a general output port, if the port is read, the
R/W _{value of this corresponding register will be read}
R/W ^{out. When the pin functions as a general input}
port, if the port is read, the status of the
R/W _{corresponding pin will be read out. However, Bit 1}
R/W is exclusively used as an output port.

input ports, the state of port3 is read from
the PJ4DT bit and the state of port4 is read
from the PJ3DT bit.
