MDI types (receive)

The sizes and offsets are in bytes, and excluding the two byte MDI header. Size S means short MDI packet. Short MDI packets need to be sent via the short MDI route and can not be send via the circular queues. (this has something to do with the register the parameters end up in inside the DSP)

This site is the result of a great deal of assembly code reading, research, countless (mostly futile) searches for data sheets, cross-referencing and analysing. If you use this information in any way please mention wumpus <blacksphere@goliath.darktech.org> (and others in the credits section) in the credits of your program/document. And tell me :) If you have more information please contribute. If you just copy this, stick your name on it and call it yours I hope you get your genitals bitten off by a three headed monkey. Have a nice day.
