Column drivers, data processing and data
latches
The column drivers section includes 132
×
3 column
outputs (C0 to C395) which should be connected directly
to the LCD. When less than 396 columns are required, the
unused column outputs must be left open-circuit.
The column output signals are generated in the data
processingblockbyreadingoutdatafromthedisplayRAM
and processing with the appropriate orthogonal function
which represents the simultaneously selected rows.
7.10
Row drivers
The row drivers section includes 132 row outputs which
should be connected directly to the LCD. When less than
132 rows are required the unused column outputs must be
left open-circuit.
When the PCF8833 is operating in full Display mode,
4 rows are always selected simultaneously. In partial
Display mode the active row output signals are selected
one after the other.
8
PARALLEL INTERFACE
The 8080-series 8-bit bidirectional interface can be used
for communication between the microcontroller and the
PCF8833. The selection of this interfaces is done with pins
PS2, PS1 and PS0; see Section 7.1.1.
The interface functions of the 8080-series parallel
interface are given in Table 86.
