The total number of bytes for a single location write command
can vary from four bytes (for a control register write), to eight
bytes (for a program RAM write). Burst mode may be used to
fill contiguous register or RAM locations. A burst mode write is
done by writing the address and data of the first RAM/register
location to be written. Rather than ending the control port
transaction (by bringing the CLATCH signal high in the
AD1940/AD1941, after the data word, as would be done in a
single address write, the next data word can be written
immediately without first writing its specific address). The
AD1940/AD1941 control ports autoincrement the address of
each write, even across the boundaries of the different RAMs
and registers.
