Port D Data Register L (PDDRL)
PDDRL is a 16-bit readable/writable register that stores port D data. Bits PD15DR to PD0DR
correspond to pins PD15 to PD0, respectively.
When a pin function is general output, if a value is written to PDDRL, the value is output directly
from the pin, and if PDDRL is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PDDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PDDRL, although that value is written into PDDRL, it
does not affect the pin state. Table 20.8 summarizes PDDRL read/write operations.
PDDRL is initialized to the respective values shown in table 20.5 by a power-on reset, but is not
initialized by a manual reset or in sleep mode or software standby mode.
