The port D control register (PDCR) is a 16-bit readable/writable register that selects the pin
functions. PDCR is initialized to H'AA8A by a power-on reset, but is not initialized by a manual
reset, in standby mode, or in sleep mode.
Bits 15 and 14—PD7 Mode 1 and 0 (PD7MD1, PD7MD0)
Bits 11 and 10—PD5 Mode 1 and 0 (PD5MD1, PD5MD0)
Bits 7 and 6—PD3 Mode 1 and 0 (PD3MD1, PD3MD0)
Bits 5 and 4—PD2 Mode 1 and 0 (PD2MD1, PD2MD0)
Bits 3 and 2—PD1 Mode 1 and 0 (PD1MD1, PD1MD0)
Bits 1 and 0—PD0 Mode 1 and 0 (PD0MD1, PD0MD0)
These bits select the pin functions and perform input pull-up MOS control.
