in pairs, triples, or quadruples. To illustrate the filling order, an example of a 7-segment
display showing all drive modes is given in
depicted applies equally to other LCD types.
The following applies to
•

•
In static drive mode the eight transmitted data bits are placed into row 0 as one byte.
In 1:2 multiplex drive mode the eight transmitted data bits are placed in pairs into
row 0 and 1 as two successive 4-bit RAM words.
In 1:3 multiplex drive mode the eight bits are placed in triples into row 0, 1, and 2 as
three successive 3-bit RAM words, with bit 3 of the third address left unchanged. It is
not recommended to use this bit in a display because of the difficult addressing. This
last bit may, if necessary, be controlled by an additional transfer to this address, but
care should be taken to avoid overwriting adjacent data because always full bytes are
transmitted (see
In 1:4 multiplex drive mode, the eight transmitted data bits are placed in quadruples
into row 0, 1, 2, and 3 as two successive 4-bit RAM words.
