13.10.1 B
ASIC COMMAND SET
The V
LCD
at T = T
CUT
in the basic command set is
determined by the conversion in the ROM look-up table
with the programmed values of V
PR
[5:0] and V
OFF
[2:0].
It can, additionally, be adjusted with the V
LCD
offset pads
V
OS
[4:0] to obtain the optimum optical performance.
Instead of using the V
LCD
offset pads (V
OP
[4:0]) the V
LCD
can be adjusted with the module maker calibration setting
MMVOPCAL[4:0]; see Chapter 22.

OMMAND SET
The V
LCD
at T = T
CUT
can be calculated with equation (5).
In the extended command set V
PR
[7:0] is the same value
as V
OP
[7:0]. It can additionally be adjusted with the V
LCD
offset pads V
OS
[4:0] to obtain the optimum optical
performance.
Instead of using the V
LCD
offset pads (V
OP
[4:0]) the V
LCD
can be adjusted with the module maker calibration setting
MMVOPCAL[4:0]; see Chapter 22.

As the programming range for the internally generated
V
LCD
allows values above the maximum allowed V
LCD
(9 V) the user has to ensure while setting the V
PR
register
and selecting the Temperature Compensation (TC), that
under all conditions and including all tolerances the V
LCD
remains below 9.0 V. This is valid for the two different
command sets.
