I'm using a J-LINK debugger with my project. It seems that some of the memory mapped registers cannot be updated (with the "RW" property), while others can.Up to now these registers include those of USART, SPI and PWM. The two pictures below show the screen of the Keil uVision4 before and after the execution of a write instruction to the MMR of SPI0DIV (addressed at 0x4000400c). You can see the MMR should be changed from 0x00 to 0x3f, and infact it didn't.
