each group of 33 data bits. The filler bit must be logic 1 when used with the self-loading mode

and a logic 0 when used in the non-self-loading mode.

DATA OUT

When the cascaded devices are used in self-load mode. The Data Out pin of the last device must

be connected to the Load Enable pin of all devices as shown in the above figure.

When two display drivers are cascaded, sufficient on-chip time delays allow the system to

operate within the specification of the device and work in a system.

Up to 10 driver inputs may be connected to the Data Out pin (pin37) of the last device.
