i.MXRT1060 FlexIO3 access with DMA

On the iMXRT1060, the FlexIO periferal can normally be accessed using eDMA. But on the i.MX RT1060 user manual, in table "Table 3-3. DMA MUX Mapping" I can find no reference to FLEXIO3 but only FLEXIO1 and FLEXIO2.

Does that mean that the FLEXIO3 peripheral cannot be used with DMA?

or is something missing in the user manual ?

Thanks in advance!

Hi Antoine Zen-Ruffinen

Yes, unfortunately, the FlexIO3 module is not accessible by the DMA peripheral, so you can only use the FlexIO1 and FlexIO2. Sorry for the inconvenience that this may cause you.

Best regards
