DMA desc. in Ref. Manual STM32F4: Possible misprint/error?

Question asked by bil.til on Jan 31, 2012
In Ref Manual DMA configuration, many register bits have the condition: "can be written only if EN=0". This is ok from my side.

But the last two bits in the list, FTH (Fifo Threshold), have the condition: "can be written only if EN=1". I think this is a misprint? (At least the StdPeriphLib-File stm32f4xx_dma.c writes them when EN=0 - so either manual wrong or procedure in stm32f4xx_dma.c wrong).
