WebWhat is bit-band operation? What is an address of the Blue LED on a TIVA TM4C123GH6PM if you are using bitband operation? Following are the contents of … WebBit-band operations use ordinary load/store instructions to read and write single bits. In CM3, bit bands are implemented in two areas. One of them is the lowest 1MB range in the SRAM area, and the second is the lowest 1MB range in the on-chip peripheral area. In addition to the addresses in these two areas can be used like ordinary RAM, they ... chisels and bits for bedrock

The memory map has two 32MB alias regions that map to two 1MB bit-band regions: Accesses to the 32MB SRAM alias region map to the 1MB SRAM bit-band region. WebIf you need to do atomic operations (not necessarily limited to bit-band ones) on non-bit-band memory, you are forced to use 'other means' to achieve the atomicity. For example you could disable all interrupts*, do the operation and then restore interrupts. That's what I had to do when porting bit-band code to stm32f7. graphite lubricant on keyboard
