(h) Pull-down resistor option register 9 (PD9)
This is a 16-bit register used to set whether to use an on-chip pull-down resistor.
This register can be read and written only in 16-bit units.
However, when using the higher 8 bits of the PD9 register as the PD9H register and the lower
8 bits as the PUD9L register, PD9 can be read and written in 8-bit and 1-bit units.
