Documentation error on DMA channels for I2C4 on STM32F7?

   On STM32F7 reference manual (RM0410, Rev 4), in the DMA stream/channel tables (p.249) there are two possible channel assignation por each I2C flow (TX or RX). For example, you can configure I2C1 to transmit using DMA1 on stream 6 channel 1 or stream 7 channel 1.

 

   However, on I2C4, according to this table, you have 3 possible channels for RX flow, and just 1 for TX flow. Is this an error in the documentation? I guess both should have to possibilities as the rest of I2C channels and they mistyped a I2C4_RX for a I2C4_TX.

 

¿If it is an error, what is the real I2C4 channels assignation?

 

Thanks.
