ADDRESSING
Data is downloaded in bytes into the RAM matrix of the
PCF8811 as indicated in Fig.2. The display RAM has
a matrix of 80 by 128 bits. The columns are addressed by
the address pointer. The address ranges are: X = 0 to 127
(1111111), Y = 0 to 9 (1001). The Y address represents
the bank number. The X and Y address which are
effectively used can be programmed thus in order to use
the PCF8811 with different display sizes without additional
loading of the microprocessor. Addresses outside these
ranges are not allowed. The icon row when enabled is
always ROW 79 and therefore located in bank 9.

Display data RAM structure
The mode for storing data into the data RAM is dependent
on the selected command set.
9.1.1
B
ASIC COMMAND SET
After a write operation the column address counter
(X address) auto-increments by one, and wraps to zero
after the last column is written. The number of columns
(X address) after which the wrap around must occur can
be programmed. The Y address counter does not
auto-increment in the basic command set, the counter
stops when a complete bank has been written to. In this
case the Y address counter must be set (Y address see
Table 5) to write the next bank (see Fig.3). When only
a part of the RAM is used both X (X max) and Y (Y max)
addresses can be set.
The data order in the basic command set is as defined in
Fig.3.
