STM32H7 DMA request mapping table

Where is the STM32H7 DMA request mapping table documented ? we want to use DMA on USART1 RX and TX.

In STm32Cube for STM32H7, example UART_HyperTerminal_DMA , the DMA mappings are:


/* Definition for USARTx's DMA */

#define USARTx_TX_DMA_STREAM DMA1_Stream7

#define USARTx_RX_DMA_STREAM DMA1_Stream5


These mappings are different from the ones defined in Table 1 of AN4031 - Using STM32xx .. series DMA controller?
