If a port D read is performed while PDDDR bits are set to
1, the PDDR values are read. If a port D read is
performed while PDDDR bits are cleared to 0, the pin
states are read.

Note: * Determined by the states of pins PD7 to PD0.
9.9.4 Port D Pull-Up MOS Control Register (PDPCR)
PDPCR controls on/off states of the input pull-up MOS of port D.
Bit Bit Name Initial Value R/W Description
7 PD7PCR 0 R/W
6 PD6PCR 0 R/W
5 PD5PCR 0 R/W
4 PD4PCR 0 R/W
3 PD3PCR 0 R/W
2 PD2PCR 0 R/W
1 PD1PCR 0 R/W
When the pin is in its input state, the input pull-up MOS of
the input pin is on when the corresponding bit is set to 1.
