The pins used for interfacing the Static Memory Controller may be multiplexed with the PIO
lines. The programmer must first program the PIO controller to assign the Static Memory Con-
troller pins to their peripheral function. If I/O Lines of the SMC are not used by the application,
they can be used for other purposes by the PIO Controller.
