Nothing in the LPC176x's UM10360 either. I'm interested in this too.
However, if looking at the DMA channels, it indicates that you can wait until a DMA channel is disabled.
Perhaps it was born out from someone looking at that ?
Anyway, since the DMACConfig register can be both read and written, I don't think it would hurt to wait for it to be enabled (well, unless you're running out of space or CPU-time).
NXP Expert comments welcome. ;)
