22.4.2
PDDR is a 16-bit readable/writable register that stores port D data. Bits PD14DR to PD0DR
correspond to pins PD14 to PD0, respectively.
If a pin is set to the general output function, that pin will output the value written to the
corresponding bit in PDDR, and the register value is read from PDDR regardless of the state of the
pin.
If a pin is set to the general input function, the pin state, not the register value, will be returned if
PDDR is read. Also, if a value is written to PDDR, although the value will actually be written, it
will have no influence on the state of the pin. Table 22.8 summarizes the PDDR read/write
operations.
Bit 15 in PDDR is reserved. This bit is read as 0. The write value should always be 0.
PDDR is initialized to H'0000 by a power-on reset or in deep standby mode. This register is not
initialized either by a manual reset or by switching to sleep mode or software standby mode.
