This is the pin for selecting parallel data input or serial data input. (This
pin has a pull-down resistor.)
P
/S= “H”: Serial data Input
P
/S= “L”: Parallel data input
The pins of the LSI have the following functions depending on the
state of
P
/S input.
When
P
/S is “H”, D0 to D5 will go into the Hi-Z state. In this condition,
the data on the lines D0 to D5 can be “H”, “L” or open. The pins
RD
(E)
and
WR
(R/
W
) should be tied to either the “H” level or the “L” level.
During serial data input, it is not possible to read the display data in the
RAM.
This is the pin for selecting whether to enable or disable the internal
oscillator circuit for the display clock. (This pin has a pull-down
resistor.)
CLS = “L”: The internal oscillator circuit is enabled.
CLS = “H”: The internal oscillator circuit is disabled (External input).
When CLS = “H”, the display clock is input at the pin CL.
This is the pin for adjusting the frequency of the internal oscillator
circuit. Connecting the pin to V
SSL
allows the oscillation frequency to
be lowered by 16%. Normally, leave this pin open.
This is the display clock input/output pin.
The function of this pin will be as follows depending on the state of and
CLS signal.
Internal cathode timing output pin
Power supply pin for the analog circuit.

Power supply pin for the organic EL anode drive circuit.
Ground pin for the organic EL anode drive circuit.
*2
Power supply pin for the organic EL cathode drive circuit.
Ground pin for the organic EL cathode drive circuit.
*2
Input pin for the anode driver output current adjusting voltage.
An input voltage is effective when EL
SEL
= “H”.
Pin that selects anode driver output current adjusting voltage. (This
pin has a pull-down resistor.)
When EL
SEL
= “L”, the internally regulated voltage is selected; when
EL
SEL
= “H”, the V
EL
pin voltage is selected.
Anode driver output current adjusting external resistor connection
pins.
