18.9.2
Port J data register (PJDR) is an 8-bit read register that stores data for pins PTJ7 to PTJ0. PJ3DT
to PJ0DT bit corresponds to PTJ3 to PTJ0 pin. When the pin function is general output port, if the
port is read the value of the corresponding PJDR bit is returned directly. When the function is
general input port, if the port is read, the corresponding pin level is read.
