20.10.2 Port J Data Register (PJDR)
The port J data register (PJDR) is an 8-bit readable/writable register that stores data for pins PTJ7
to PTJ0. Bits PJ7DT to PJ0DT correspond to pins PTJ7 to PTJ0. 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. Table
20.18 shows the function of PJDR.
PJDR is initialized to H'00 by a power-on reset. It retains its previous value in software standby
mode and sleep mode, and in a manual reset.
