10.12.7  Port D Input Pull-Up MOS States 
Port D has a built-in input pull-up MOS function that can be controlled by software. This input 
pull-up MOS function can be used in modes 3 and 7. The input pull-up MOS can be specified as 
on or off on a bit-by-bit basis. 
In modes 3 and 7, when a PDDDR bit is cleared to 0, setting the corresponding PDPCR bit to 1 
turns on the input pull-up MOS for that pin. 
Table 10.6 summarizes the input pull-up MOS states.
