LCD driver for low multiplex rates
Fig 15. Bank selection
In the static drive mode, the bank-select command may request the contents of row 2 to
be selected for display instead of the contents of row 0. In the 1:2 multiplex mode, the
contents of rows 2 and 3 may be selected instead of rows 0 and 1. This gives the
provision for preparing display information in an alternative bank and to be able to switch
to it once it is assembled.
In Figure 16 an example is shown for 1:2 multiplex drive mode where the displayed data is
read from the first two rows of the memory (bank 0), while the transmitted data is stored in
the second two rows of the memory (bank 1).
