Conversely writing a value of 0 will clear the bit-band bit.

WebHi there, 1) Bit band and data cache doesn't match very well. One of the bit band address ranges is in SRAM region and is cacheable, With bit band, the same information is available from two address spaces and if we need to support this, the data cache need to remap the address on the fly which can be problematic.
