xxxxxxxx&nbsp; x: address</TT>

<P>This isn't a DMA register at all, but is often used in conjunction with
DMA to do memory-to-memory or memory-fill operations.&nbsp; This is a fairly
simple register, but I'm documenting it here because it's not fully covered
anywhere else.&nbsp; A write or a read to this register causes a read/write
to the specified address, and every time a read/write occurs, the address
part of the register is incremented by one, including the MSB.

<P>Important: The x bits (address) see
