Let's make a counter
This sample program explains how to make a simple counter using FRAM. The counter
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).
9.1 Overview of the sample program
This sample program creates a counter using the FRAM and the functions of the serial
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.
Because the count is stored in FRAM, even if the power is turned off during operation by
disconnecting the USB cable, the counter will resume counting, when power is restored, exactly
from where it left off before losing power.
Figure 11.1-1 shows the operation and details of the sample program.
