PCF8536
Universal LCD low multiplex driver with 6 channel PWM generator
? the RAM columns and the segment outputs,
? the RAM rows and the backplane outputs.
The display RAM bit map, Figure 20 , shows row 0 to row 7 which correspond with the
backplane outputs BP0 to BP7, and column 0 to column 43 which correspond with the
segment outputs S0 to S43. In multiplexed LCD applications, the data of each row of the
display RAM is time-multiplexed with the corresponding backplane (row 0 with BP0, row 1
with BP1, and so on).
When display data is transmitted to the PCF8536, the display bytes received are stored in
the display RAM in accordance with the selected LCD multiplex drive mode. The data is
stored as it arrives and depending on the current multiplex drive mode, data is stored in
quadruples, sextuples or bytes.
8.9.1 Data pointer (LCD part)
The addressing mechanism for the display RAM is realized using the data pointer. This
allows the loading of an individual display data byte, or a series of display data bytes, into
any location of the display RAM. The sequence commences with the initialization of the
data pointer by the load-data-pointer-LCD command (see Table 25 ).
Following this command, an arriving data byte is stored starting at the display RAM
address indicated by the data pointer.
The data pointer is automatically incremented in accordance with the chosen LCD
multiplex drive mode configuration. That is, after each byte is stored, the contents of the
data pointer are incremented
? by two (1:4 multiplex drive mode),
? by one or two (1:6 multiplex drive mode),
? by one (1:8 multiplex drive mode).
Multiplex drive 1:6 is a special case and is described later on.
When the address counter reaches the end of the RAM, it stops incrementing after the last
byte is transmitted. Redundant bits of the last byte and subsequent bytes transmitted are
discarded until the pointer is reset. To send new RAM data, the data pointer must be reset.
If an I 2 C-bus or SPI-bus data access is terminated early then the state of the data pointer
is unknown. The data pointer must then be re-written prior to further RAM accesses.
