Port D Control Register (PDCR) is a 16-bit read/write register that selects the pin functions.
PDCR is initialized to H'AAAA by power-on resets; however, it is not initialized by manual
resets, in standby mode, or in sleep mode.
Bits 15, 14: PD7 Mode 1, 0 (PD7MD1, PD7MD0)
Bits 13, 12: PD6 Mode 1, 0 (PD6MD1, PD6MD0)
Bits 11, 10: PD5 Mode 1, 0 (PD5MD1, PD5MD0)
Bits 9, 8: PD4 Mode 1, 0 (PD4MD1, PD4MD0)
Bits 7, 6: PD3 Mode 1, 0 (PD3MD1, PD3MD0)
Bits 5, 4: PD2 Mode 1, 0 (PD2MD1, PD2MD0)
Bits 3, 2: PD1 Mode 1, 0 (PD1MD1, PD1MD0)
Bits 1, 0: PD0 Mode 1, 0 (PD0MD1, PD0MD0)
These bits select the pin functions and the input pullup MOS control.
