8.13 Timing generator

The timing generator produces the various signals required to drive the internal circuitry.

Internal chip operation is not disturbed by operations on the data buses.

8.14 LCD row and column drivers

The PCF2113x contains 18 row and 60 column drivers, which connect the appropriate

LCD bias voltages in sequence to the display in accordance with the data to be displayed.

R17 and R18 drive the icon rows.

The bias voltages and the timing are selected automatically when the number of lines in

the display is selected. Figure 14, Figure 15, Figure 16 and Figure 17 show typical

waveforms. Unused outputs should be left unconnected.
