functionality is achieved by using the SPI communications function on the multifunction serial
interface (MFS), on the microcontroller (MB91F662) on this starter kit, to access the stand-alone
FRAM MB85RS256 (256 kbit).
interface on the MB91F662. The FRAM is used to store counter data, while the pushbutton
switches are used to increment and clear the count, and toggle the 7-SEG LED display ON or
OFF.
disconnecting the USB cable, the counter will resume counting, when power is restored, exactly
from where it left off before losing power.
