(c) Port CD function control register (PFCCD)
This register can be read/written in 8-bit or 1-bit units. Bits 7 to 4, 1, and 0, however, are fixed to 0, so
writing 1 to these bits is ignored.
Caution When the port mode is specified by the port CD mode control register (PMCCD), the
PFCCD setting becomes invalid.
