The pins used for interfacing the Static Memory Controller are multiplexed with the PIO lines.
The programmer must first program the PIO controller to assign the Static Memory Controller
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.
The SMC is clocked through the Power Management Controller (PMC), thus the programmer
must first configure the PMC to enable the SMC clock.
