#98976 - E5
Responding to: ???'s previous message
The Triscend E5 (now Zylogic ZE5) had a DMA controller - you could take a look at that for some ideas?

Basically, you just need a set of registers to control the DMA (source address, destination address, length, etc) and an interrupt (or status register) to tell the processor when it's done.

As you're working with a "soft" 8051, you presumably have the choice of whether you map the registers into SFR or XDATA space?
See your documentation for details...
