PIN FUNCTIONS
7.1
ROW 0 to ROW 47 row driver outputs
These pads output the display row signals.
7.2

V
SS1
and V
SS2
: negative power supply rails
Negative power supply rails V
SS1
and V
SS2
must be
connected together, hereafter referred to as V
SS
. When a
pin has to be connected externally to V
SS
, then pin V
SS1
should be used.

: LCD power
supply
If the internal V
LCD
generator is used, then all three pins
must be connected together. If not (V
LCD
generator is
disabledandanexternalvoltageisappliedtoV
LCDIN
),then
V
LCDOUT
must be left open-circuit, V
LCDSENSE
must be
connected to V
LCDIN
, V
DD2
and V
DD3
should be applied
according to the specified voltage range. The following
settings are also required: HVE = 0, S
1
= 1 and S
0
= 0.
7.6
V
OS4
to V
OS0
: calibration inputs
Five pull-up input pins for on-glass V
LCD
calibration. Each
pin may be connected to V
SS
, which corresponds to
logic 0, or left open-circuit, which corresponds to logic 1.
All five pins define a 5-bit two’s complement number
ranging from
16 to 15 decimal (from 10000 to 01111).
The default value, with all pins connected to V
SS
, is
0 decimal (00000).
