	~~Currently not supported by latest~~ core 3.0.7		since core 3.1.2 this port $0B is '''supported''' and always in "Zilog DMA" mode, for "zxnDMA" use {{PortNo\|$xx6B}}.
	~~(unclear whether it was ever~~ supported in ~~some older 2~~.~~0 cores, or the support was just planned, but currently not working at all)~~

	If you have DMA app expecting the port to be $0B, you have to patch it to use the new data-gear port $6B. Also keep in mind the zxnDMA is by default in zxnDMA mode, while all the regular MB-02 SW does expect Zilog-like functionality, so the Next has to be reconfigured first by bit 6 of {{NextRegNo\|$06}} before running the app.		<del>Currently not supported by latest core 3.0.7
