* Note: burst read/write settings of the following FBCS are purely "cosmetical".
* The Coldfire FlexBus only "bursts" on a smaller port size than 32 bit up to 32 bit,
* i.e. it can burst on an 8 bit port up to 4 burst cycles or two on a 16 bit port.
* Enabling burst on a 32 bit port has no effect (unfortunately).
