Two 1MB 'bit-band' regions, one in the peripheral memory area and one in the SRAM memory areas are each mapped to a 32MB virtual 'alias' region. Each bit in the bit-band region is mapped to a 32bit word in the alias region. The first bit in the 'bit-band' peripheral memory is mapped to the first word in the alias … See more Bit Banding is a method of performing atomic bitwise modifictions to memory.If you have used small PIC micros before these are like BSF and BCF (Bit Set and Bit Clear) See more <>Define base address of bit-band 1. define BITBAND_SRAM_BASE 0x20000000Define base address of alias band 2. define … See more Usually changing a word in memory requires a read-modify-write cycle.
