Direct Memory Access uses the ST10 MAC for address generation in externalmemory-external memory transfers. This application note supplies the machine code forexternal memory - ST10 internal memory transfers, and for external memory-externalmemory transfers made by Direct Memory Access using the MAC. For reference, the ST10long addressing mode is summarized.The ST10 instruction set contains special MAC instructions and two new addressing modeswhich supply the MAC with up to 2 new operands per instruction. The MAC contains a 16x16multiplier, 40 bit accumulator a repeat unit and an address generator.
