6.8
This pin is for oscillator frequency selection. A resistor must be connected between this pin and V
DD
when using the internal oscillator. The suggested value of the resistor is 680K ohm. Please refer to the
Figure 8 for details.
OSC1
6.9
This pin is an input pin to enable the internal reference voltage used for the internal regulator. When it
is high, an internal reference voltage source will be used. When it is low, and external reference must
be provided in V
EXT
.

DD
Digital and Analog power supply pins, must be connected to same external source.
6.11 V
DD
Internally connected to DV

SS
Digital and Analog ground, must be connected to external ground.
6.13 V
SS
Internally connected to DV
SS
for pull low purpose.
6.14 V
CI
Reference voltage input for internal DC-DC converter. The voltage of generated V
CC
equals to the
multiple factor (3X, 4X or 5X) times V
CI
with respect to V
SS
.
Note: Voltage at this input pin must be larger than or equal to AV
DD
and DV
DD.
6.15 V
CC
Voltage at this pin must be greater then V
L4
+ 2V. It can be supplied externally or generated by the
internal DC-DC converter.
When using internal DC-DC converter as generator, voltage at this pin is for internal reference only. It
CANNOT be used for driving external circuitries.

L7
This pin is the most positive LCD driving voltage. It can be generated by the internal regulator or
supply externally when internal regulator and divider are turned off.
6.18 V

This pin is an input to provide an external voltage reference for the internal voltage regulator when
REF pin is pulled low.
