PARALLEL INPUT/OUTPUT PORTS
Pins PD5, PD6 and PD7 have internal pull-up resistors connected to VDD.
Conguration of Port D is done via the Port D Mode Register ($0012).
If a bit is set in the mode register, the corresponding port bit is used only as an output irrespective
of the value in the data direction register (see Table 6-2).
Figure 6-3 shows the internal structure of Port D.
