Eight-bit transmissions are write-only, data-only
accesses that write data to the display memory indi-
rected by the global display indirect address register
(Figure 6). The global display indirect address register
autoincrements after the write access. Eight-bit trans-
missions provide the quickest method of updating a
plane of display memory of the MAX6960. It is the most
suitable display update method if the host system
builds an image in local memory, and then dumps the
image into a display plane of the MAX6960.
Sixteen-bit transmissions are read/write, command-
and-data accesses to the MAX6960’s configuration
registers (Figure 7). A write can generally be global
(updates all MAX6960s on the 4-wire bus with the same

data) or specific (updates just the MAX6960 indirected
by the global driver indirect address register). Note:
The global driver indirect address register selects a
specific MAX6960. This is not the same as the glob-
al display indirect address register, which points to
display memory that could be in any MAX6960. A
16-bit read is always indirected through the global dri-
ver indirect address register to select only one
MAX6960 to respond. When a read or write is indirect-
ed through the global driver indirect address register,
the 16-bit command can choose whether the global dri-
ver indirect address is autoincremented after the com-
mand has been executed. This allows the host to set up
one or more registers in consecutive MAX6960s with
the display indirect address, autoincrementing only
when required.
