-	This example application demonstrates the use of the bit-banding capabilities of the Cortex-M3 microprocessor. Some of SRAM and all of the GPIO registers reside within bit-band regions, meaning that bit-banding operations can be applied to any of them. In this example, a location in SRAM is read then bit-banding is used to clear and set bit 3 of the SRAM location.

When the program is started a message will be printed to the terminal.

This example application demonstrates the use of the bit-banding capabilities of the Cortex-M3 microprocessor. All of SRAM and all of the peripherals reside within bit-band regions, meaning that bit-banding operations can be applied to any of them. In this example, a variable in SRAM is set to a particular value one bit at a time using bit-banding operations (it would be more efficient to do a single non-bit-banded write; this simply demonstrates the operation of bit-banding).
