[Area Scroll Setup Example]
In the center screen scroll of 1/120 duty (display range: 120 lines = 30 blocks), if 8 lines = 2 blocks and 8 lines = 2 blocks
are specified for the top and bottom FIX areas, 104 lines = 26 blocks is specified for the scroll areas, respectively, 12
lines = 3 blocks on the DDRAM are usable as the background area. Value of each parameter at this time is as shown
below.

(20) Scroll start address set (SCSTART) Command: 1 Parameter: 1
This command and succeeding parameter are used to specify the start block address of the scroll area. Note that you
must execute this command after executing the area scroll set command. Scroll becomes available by dynamically
changing the start block address.

(23) Power control set (PWRCTR) Command: 1 Parameter: 1
This command is used to turn on or off the liquid crystal driving power circuit, booster/step-down circuits and voltage
follower circuit.
*: Invalid bits irrelevant to the operations.
P10:It turns on or off the Reference voltage generation circuit.
P10 = “1”: ON. P10 = “0”: OFF.
P11:It turns on or off the voltage regulator and circuit voltage follower.
P11 = “1”: ON. P11 = “0”: OFF.
Note: 2 bits of P10 and P11 must be turned on or off simultaneously.
P12:It turns on or off the secondary booster/step-down circuit.
P12 = “1”: ON. P12 = “0”: OFF.
P13:It turns on the primary booster circuit.
P13 = “1”: ON. P13 = “0”: OFF.
P14: It is used to select either external resistance using the V
R
terminal or control via EEPROM access to adjust V
1
voltage.
P14 = “1”: External resistance P14 = “0”: EEPROM
