14.10. Bit-band accesses

The System bus interface contains logic that controls bit-band accesses as follows:

For more information about bit-banding, see Bit-banding.


  • The CM3Core does not stall during bit-band operations unless it attempts to access the System bus while the bit-band operation is being carried out.

  • Big endian accesses to the bit-band alias region must be byte-sized. Otherwise, the accesses are Unpredictable.
