Application: Demonstrate how you can use C code with a simple pre-processor macro to perform Bit-banding operation
BSP Version: M480 Series BSP CMSIS V3.03.000
Hardware: NuMaker-ETM-M487 v1.1
Bit-banding is a feature of the Cortex-M4 processor that maps each word in an alias region of memory to a bit in a bit-band region of memory. This allows an individual bit in SRAM or peripheral register to be set/cleared by a single instruction that increases the operation speed.
This sample demonstrates how to use Bit-banding operation in C with a simple pre-processor macro to perform the accesses.
