Universal LCD driver for multiplex rates up to 1:8

Depending on the start address of the data pointer, there is the possibility for a boundary

condition. This occurs when more data bits are sent than fit into the remaining RAM. The

additional data bits are discarded. See Figure 21.

8.9.3 RAM filling in 1:6 multiplex drive mode

In the 1:6 multiplex drive mode the RAM is organized in six rows and 42 columns. The

eight transmitted data bits are placed in such a way, that a column is filled up (see

Figure 22).
