DMA in LPC11U6x

I see that the user manual of the LPC11U68, Rev. 1.4 — 28 October 2015 at page 8 of 610 doesn't permit the connection of the HI speed GPIO (PIN port) as a source of a DMA data transfer because HS GPIO+ block is not gray shaded. However on page 15 of the same doc, the HS GPIO port is connected to the DMA, and usually, the high speed GPIO ports of the LPC17xx, LPC18xx etc.. can be connected to the DMA.

Do you confirm that the high speed GPIO ports of the LPC11U68 can't be connected to the DMA (as a source data port) ?
