Initialization
See the section describing each port for examples of initialization of the ports.
Note:
It is recommended that when initializing the port, the data latch (PORT register)
should be initialized first, and then the data direction (TRIS register). This will elim-
inate a possible pin glitch, since the PORT data latch values power up in a random
state.
