7.11
Character Generator ROM (CGROM)
The CGROM generates 240 character patterns in a
5
×
8 dot format from 8-bit character codes.
Figures 7, 8, 9 and 10 show the character sets that are
currently implemented.
7.12
Character Generator RAM (CGRAM)
Up to 16 user defined characters may be stored in the
CGRAM. Some CGRAM characters (see Fig.16) are also
used to drive icons (6 if icons blink and both icon rows are
used in the application; 3 if no blink but both icon rows are
used in the application; 0 if no icons are driven by the icon
rows). The CGROM and CGRAM use a common address
space, of which the first column is reserved for the
CGRAM (see Fig.7). Figure 11 shows the addressing
principle for the CGRAM.
7.13
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.
7.14
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.
7.15
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 12, 13, 14 and 15 show typical
waveforms. Unused outputs should be left unconnected.
