#USE FIXED_IO (port_outputs=pin, pin?)
port is A-G, pin is one of the pin constants defined in the devices .h file.
This directive affects how the compiler will generate code for input and output
instructions that follow. This directive takes effect until another #USE XXX_IO
directive is encountered. The fixed method of doing I/O will cause the compiler to
generate code to make an I/O pin either input or output every time it is used. The
pins are programmed according to the information in this directive (not the
operations actually performed). This saves a byte of RAM used in standard I/O.
When linking multiple compilation units be aware this directive only applies to the
current compilation unit.

#USE FAST_IO (port)
port is A, B, C, D, E, F, G, H, J or ALL
Affects how the compiler will generate code for input and output instructions that
follow. This directive takes effect until another #use xxxx_IO directive is
encountered. The fast method of doing I/O will cause the compiler to perform I/O
without programming of the direction register. The compiler's default operation is
the opposite of this command, the direction I/O will be set/cleared on each I/O
operation. The user must ensure the direction register is set correctly via
set_tris_X(). When linking multiple compilation units be aware this directive only
applies to the current compilation unit.
