Section 35
35.4.2
PDDR is a register that stores data for pins PTD7 to PTD0. Bits PD7DT to PD0DT correspond to
pins PTD7 to PTD0. When the pin function is general output port, if the port is read, the value of
the corresponding PDDR bit is returned directly. When the function is general input port, if the
port is read, the corresponding pin level is read.
