PCF2104x
8.14
Programming of MUX 1 : 16 displays with
PCF2104x
The PCF2104x can be used in the following ways:
• 1-line mode to drive a 2-line display
• 2 × 12 characters with MUX rate 1 : 16, resulting in
better contrast. The internal data flow of the chip is
optimized for this purpose.
Using the ‘Function set’ instruction, M and N are set to 0, 0
(respectively). Figures 12, 13 and 14 show the DDRAM
addresses of the display characters. The second row of
each table corresponds to either the right half of a 1-line
display or to the second line of a 2-line display. Wrap
around of data during display shift or when writing data is
non-standard.
