MAX6960s in a display-driver design not only share the
host 4-wire interface, but they also share a local 3-wire
interface that is not connected to the host. The local 3-
wire interface works with the user’s driver settings to con-
figure all the MAX6960s to appear to the host interface as
one contiguous memory-mapped driver.
The pixel level-intensity control uses frame modulation.
Pixels are enabled and disabled on a frame-by-frame
basis over a 12-frame super frame (Table 5). The effec-
tive pixel frame duty cycle within a super frame sets each
pixel’s effective intensity. The 12-frame period of a super
frame allows arithmetic and geometric intensity scales to
be mixed on the same driver. This allows the user to set
up an RGY display with a different color scale for red and
green. The MAX6960 uses display memory planes to
