DMA2 controller
The 5 requests from the peripherals (TIMx[5,6,7,8], ADC3, SPI/I2S3, UART4,
DAC_Channel[1,2]and SDIO) are simply logically ORed before entering to the DMA2, this
means that only one request must be enabled at a time. Refer to Figure 24: DMA2 request
mapping .
The peripheral DMA requests can be independently activated/de-activated by programming
the DMA control bit in the registers of the corresponding peripheral.
Note:
The DMA2 controller and its relative requests are available only in high-density and
connectivity line devices.
