I'm learning about stm32 MCU handling. stm32f0-discovery platform with stm32f072rb MCU.

I have a questions about DMA.

1. How to modify transfer direction? I try to modify DIR bit in CCMR1, but setting is rejected.

2. I have only one DMA1_Channel1->CMAR register. How to achieve memory to memory transfer. I should have two different memory address, source and target.
