7.10
V
OS4
to V
OS0
These 5 input pins enable the calibration of the
programmed V
LCD
(can be connected on the module to
V
DD1
or V
SS1
).
7.11
EXT: extended command set
Input to select the basic command set or the extended
command set. Must be connected on the module to have
only one command set enabled.
Table 1
Command set
Note:
Philips strongly recommends that the extended
command set be used.
7.12
PS0, PS1 and PS2
Parallel/serial/I
2
C-bus interface selection.
Table 2
Interface selection
7.13
D/C
Input to select either command/data or data input. Not
used in the 3-line serial interface, 3-line SPI and I
2
C-bus
interface and must be connected to V
DD1
or V
SS1
.
7.14
R/W
Input to select read or write mode when the 6800 parallel
interface is selected. Not used in the serial and I
2
C-bus
mode and must be connected to V
DD1
or V
SS1
.
7.15
E
E is the clock enable input for the 6800 parallel bus. Not
used in the serial or I
2
C-bus interface and must be
connected to V
DD1
or V
SS1
.
7.16
SCLH/SCE
Input to select the chip and so allowing data/commands to
be clocked in or serial clock input when the I
2
C-bus
interface is selected.
7.17
SDAH
I
2
C-bus serial data input. When not used it must be
connected to V
DD1
and V
SS1
.
7.18
SDAHOUT
SDAHOUT is the serial data acknowledge output for the
I
2
C-bus interface. By connecting SDAHOUT to SDAH
externally, the SDAH line becomes fully I
2
C-bus
compatible. Having the acknowledge output separated
from the serial data line is advantageous in COG
applications. In COG applications where the track
resistance from the SDAHOUT pad to the system SDAH
line can be significant, a potential divider is generated by
the bus pull-up resistor and the ITO track resistance. It is
possible that during the acknowledge cycle the PCF8811
will not be able to create a valid logic 0 level. By splitting
the SDAH input from the SDAHOUT output the device
could be used in a mode that ignores the acknowledge bit.
In COG applications where the acknowledge cycle is
required, it is necessary to minimize the track resistance
from the SDAHOUT pad to the system SDAH line to
guarantee a valid low level. When not used it must be
connected to V
DD1
or V
SS1
.
7.19
DB7 to DB0
These input/output lines are used by the several interfaces
as described below. When not used in the serial interface
or the I
2
C-bus interface it must be connected to V
DD1
or
V
SS1
.
7.19.1
DB7
TO
DB0 (
PARALLEL INTERFACE
)
8-bit bidirectional bus. DB7 is the MSB.
7.19.2
DB7, DB6
AND
DB5 (
SERIAL INTERFACE
)
DB7 is used for serial input data (SDATA) when the serial
interface is selected. DB6 (SCLK) is used for the serial
input clock when the serial interface is selected. DB5 is
used as the serial output of the serial interface (SDO).
7.19.3
DB3
AND
DB2 (I
2
C-
BUS INTERFACE
)
DB3 and DB2 are respectively the SA1 and SA0 inputs
when the I
2
C-bus interface is selected and can be used so
that up to four PCF8811s can be distinguished on one
I
2
C-bus interface.
