WebThis is called 'mapping' and the bit-band address region is called an 'alias'. Seems strange, doesn't it. If the HSION bit is set, then its address in the bit-band region contains the value 0x00000001 (a 4-byte location for every aliased bit); if it is reset, then the corresponding value in the bit-band region is 0x00000000.

"WebThe processor performs the access to the bit-band alias address, but this does not result in a bit-band operation. For example, an unaligned halfword access to 0x21FFFFFF is performed as a byte access to 0x21FFFFFF followed by a byte access to 0x22000000 (the first byte of the bit-band alias). Unaligned loads that match against a literal ... " - Bit band operation

Bit band operation

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 ...

WebThe processor does not stall during bit-band operations unless it attempts to access the System bus while the bit-band operation is being carried out. 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. WebBit-band operations are only possible in the bit-band regions where the LSB of each word represents a single bit in a bit-band alias region. The term "bit-band alias" describes …
