(c) Port mode control register 3 (PMC3)
This is a 16-bit register used to specify the port mode/control mode.
This register can be read and written only in 16-bit units.
However, when using the higher 8 bits of the PMC3 register as the PMC3H register and the lower
8 bits as the PMC3L register, PMC3 can be read and written in 8-bit and 1-bit units.
