PARALLEL INTERFACES
The parallel interface is an 8-bit bidirectional interface for
communication between the microcontroller and the LCD
driver chip. Two different parallel interfaces can be
selected by the inputs PS2, PS1 and PS0.
8.1
6800-type parallel interface
The interface functions of the 6800-type parallel interface
are shown in Table 2.
Table 2
6800-type parallel interface function
The 6800-type parallel interface can be configured to have
the clock connected to the Enable input (E) with timing as
shown in Fig.38, or with the clock connected to the chip
select input (SCE) and the Enable (E) is tied HIGH with
timing as shown in Fig.39. The PCF8813 is capable of
detecting these different modes automatically.
8.2
8080-type parallel interface
Table 3 shows the interface functions of the 8080-type
parallel interface.

SERIAL INTERFACES
Communication with the microcontroller can also be via a
clock-synchronized serial peripheral interface. It is
possible to select two different 3-line interfaces (SPI and
serial interface) or a 4-line serial interface (SPI). Selection
of the interface is made with the inputs PS2, PS1 and PS0
(see Section 7.1).
9.1
Serial peripheral interface
The Serial Peripheral Interface (SPI) is a 3-line or 4-line
interface for communication between the microcontroller
and the LCD driver. The 3-line interface requires a chip
enable input (SCE), serial clock (SCLK) and serial
data (SDATA). For the 4-line serial interface, a separate
D/C line is added. The PCF8813 is connected to the serial
data I/O (SDATA) of the microcontroller via the pads data
input (SDATA) and data output (SDOUT) connected
together.
9.1.1
W
RITE MODE
The display data/command indication may be controlled
viasoftwareorbytheD/C selectinput.WhentheD/C input
is used, display data is transmitted when D/C is HIGH, and
command data is transmitted when D/C is LOW (see
Figs 15 and 16). When D/C is not used, the display data
length instruction is used to indicate that a specific number
of display data bytes (1 to 256) are to be transmitted (see
Fig.17). The byte that follows the display data string is
handled as an instruction command.
If SCE is pulled HIGH during a serial display data stream,
the interrupted byte is invalid data but all previously
transmitted data is valid. The next byte received will be
handled as an instruction command (see Fig.18).
