DMA Microcode on the MCF5475

Does anyone know whether there is any documentation available to help write your own microcode for the MCF5475 DMA controller?

I'm aware of the Multi-Channel DMA API, but that just lets me choose from a number of pre-written functions where Freescale have already written the microcode. I'm interested in exploring whether we can use our own microcode for an application with very precise timing requirements. Is this documented anywhere?
