ARM Cortex-M3 features a 1 MB area in SRAM memory called bit-band region. In this region each bit can be accessed individually. To … See more Now, if you allocate a dedicated integer variable for each flag, then you will end up with running out the free memory space. In this case bit-field … See more

ARM: Using bit-banded memory from C or C++ - Stack …
WebNow I can nicely use the command. This generally is very nice - just I am disturbed that I have to define this BITNR_UIF. It would be very nice to get the BitNumber from the STM32F4xx.h mask definition somehow automatically by some macro. Converting BitNumber to BitMask is easy with the 1< WebLarger design size. ARM recommends that bit level access functionality is designed into any peripherals that can benefit from fast bit set and clear operations rather than using the bit-band wrapper. Figure 3.20 shows the AHB bit-band wrapper module for the Cortex-M0 and Cortex-M0+ processor. Figure 3.20. AHB bit-band wrapper for Cortex-M0 and ... WebThe bit band mechanism works by using a separate memory region called the bit-band alias. Alias regions are located far from available RAM or actual peripherals.
