WebJul 14, 2010 · There are two regions of memory that have bit-band alias regions. First there is a 1Mbyte SRAM region from 0x20000000 – 0x20100000 where each bit is aliases by a byte address in the range 0x22000000 – 0x23FFFFFF. Then there is the peripheral space from 0x40000000 – 0x40100000 which is aliased in the same way to the range …

LD Scripts is the best approach for BitBanding with GCC?

WebDec 1, 2011 · The first bit in the 'bit-band' peripheral memory is mapped to the first word in the alias region, the second bit to the second word etc. Writing a value to the alias region with Least Significant Bit i.e. bit [0] set to 1 will write a value of 1 to the bit-band bit. Conversely writing a value of 0 will clear the bit-band bit. WebFor example, writing to one of the alias words will set or clear the corresponding bit in the bitband region. It appears to be a way to get single bit atomic operation. When writing to the alias regions bit 0 of the 32 bit word is used to set the value at the bit-banding region. Reading from the alias address will return the value from the bit ...
