Bit band operation
Did you know?
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 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 ...

Fitbit Inspire 2 ... cam strap vs ratchet strapWebThe 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. fish and chips red deerWebNote that all bit operations return signed 32 bit numbers . And these print as signed decimal numbers by default. For clarity the examples assume the definition of a helper function printx(). This prints its argument as an unsigned 32 bit hexadecimal number on all platforms: function printx(x) print("0x"..bit.tohex(x)) end Bit Operations fish and chips reddingWeb6.7.4 Bit-band operations in C programs.

For example you could disable all interrupts*, do the operation and then restore interrupts.
