the high byte is always $21; e.g. if you set it to $18, the transfer destination
will be $2118.&nbsp; The <A HREF="#Reg43x0">DMA control register</A> controls
how the bytes will be transferred.&nbsp; Using the previous example, setting
it to one(1) will cause bytes written to alternate between $2118 and $2119.&nbsp;
Use $43?0 to start a transfer.&nbsp; For instance, if you were using DMA
channel 1 ($4310, etc.), you would set bit one in that register. (e.g.
LDA #$2 \ STA $420B.)
