Section 18 I/O Ports
18.4.2
Port D data register (PDDR) is an 8-bit read/write register that stores data for pins PTD7 to PTD0.
PD7DT to PD0DT bit corresponds to PTD7 to PTD0 pin. 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.
PDDR is initialized to H'00 by a power-on reset. It retains its previous value in standby mode and
sleep mode, and in a manual reset.
