stm32l011x.h and 21 Missing DMA1_Channel6/7

V1.5.0 for L011 and L021 miss following defines:

#define DMA1_Channel6       ((DMA_Channel_TypeDef *) DMA1_Channel6_BASE) #define DMA1_Channel7       ((DMA_Channel_TypeDef *) DMA1_Channel7_BASE) RM0377 Rev5 tells that DMA1 for Cat 1 devices is full featured, so this contradicts ''full-featured''. Dataseeht also tells about 7-channel DMA controller. Please correct this inconsistancy

Hi bonnes.uwe,

•In the RM0377 (Rev5), section 10: Direct memory access controller (DMA): “The DMA controller has up to 7 channels (except for category 1 devices which feature up to 5 channels)â€�•In the STM32L011x3/4 and STM32L021x4 datasheets, paragraph 3.9 Direct memory access (DMA):â€� The flexible 5-channel, general-purpose DMA is able to manage memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers.â€� But I confirm that there is a typo in the first page of datasheets and it will be corrected later.-Syrine-
