22.1.4 Port D Control Register (PDCR)
PDCR is a 32-bit readable/writable register that selects the pin functions. PDCR is initialized to
H'00000000 (MD3 = 0, 16-bit bus width) or H'FFFFFFFF (MD3 = 1, 32-bit bus width) by a
power-on reset, and it is not initialized by a manual reset, in standby mode, or in sleep mode.
