9.5
Normal/icon mode operation
9.6
Direct mode
When DM = 0, the chip is not in direct mode. Either the
internal voltage generator or an external voltage may be
used to achieve the necessary V
LCD
value.
When DM = 1, the chip is in direct mode. The internal
voltage generator is turned off and the V
LCD
output is
directly connected to the HVgen supply voltage V
DD2
.
The direct mode can be used to reduce the current
consumption when the required V
LCD
output voltage is
close to the V
DD2
supply voltage. This can be the case in
icon mode or in Mux 1 : 9 (depending on LCD liquid
properties).
9.7
Voltage multiplier control
S[1:0]
A software configurable voltage multiplier is incorporated
and can be set via ‘Set HVgen stages’ command.
The voltage multiplier control can be used to reduce
current consumption by disconnecting internal voltage
multiplier stages (depending on the required V
LCD
output
voltage).
9.8
Screen configuration
L: default is L = 0.
L = 0: the two halves of a split screen are connected in a
standard way i.e. column 1/81, 2/82 to 80/160.
L = 1: the two halves of a split screen are connected in a
mirrored way i.e. column 1/160, 2/159 to 80/81. This
allows single layer PCB or glass layout.
9.9
Display configuration
P, Q: default is P, Q = 0.
P = 1: mirrors the column data.
Q = 1: mirrors the row data.
9.10
TC1 and TC2
Default is TC1 and TC2 = 0. This selects the default
temperature coefficient for the internally generated V
LCD
.
TC1 and TC2 = 10, 01 and 11 selects alternative
temperature coefficients 1, 2 and 3 respectively.
9.11
Set V
LCD
TheV
LCD
valueisprogrammedbyinstruction.Twoon-chip
registers hold V
LCD
values for the character mode and the
icon mode respectively (V
A
and V
B
). The generated V
LCD
value is independent of V
DD
, allowing battery operation of
the chip.
V
LCD
programming:
1.
Send ‘function set’ instruction with H = 1
2.
Send ‘set V
LCD
’ instruction to write to voltage register:
a) DB7, DB6 = 10: DB5 to DB0 are V
LCD
of character
mode (V
A
)
b) DB7,DB6 = 11:DB5 to DB0areV
LCD
oficonmode
(V
B
)
c) DB5 to DB0 = 000000 switches V
LCD
generator off
(when selected)
d) During ‘display off’ and power-down the V
LCD
generator is also disabled.
3.
Send ‘function set’ instruction with H = 0 to resume
normal programming.
9.12
Reducing current consumption
Reducing current consumption can be achieved by one of
the options given in Table 11.
When V
LCD
lies outside the V
DD
range and must be
generated, it is usually more efficient to use the on-chip
generator than an external regulator.
