Product specification
LCD controller/driver
PCF2113x
8.14
Cursor control circuit
The cursor control circuit generates the cursor (underline
and/or cursor blink as shown in Fig.6) at the DDRAM
address contained in the Address Counter. When the
Address Counter contains the CGRAM address the cursor
will be inhibited.
8.15
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.
8.16
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. Figures 11, 12 and 13 show typical waveforms.
Unused outputs should be left unconnected.
