(b) Port mode register 9 (PM9)
This is a 16-bit register used to specify the input mode/output mode.
This register can be read and written only in 16-bit units.
However, when using the higher 8 bits of the PM9 register as the PM9H register and the lower
8 bits as the PM9L register, PM9 can be read and written in 8-bit and 1-bit units.
(c) Port mode control register 9 (PMC9)
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 PMC9 register as the PMC9H register and the lower
8 bits as the PMC9L register, PMC9 can be read and written in 8-bit and 1-bit units.
