DSTB SLP STB
SLP: When SLP = 1, ILI9325 enters the sleep mode and the display operation stops except the RC oscillator
to reduce the power consumption. In the sleep mode, the GRAM data and instructions cannot be
updated except the following two instructions.
a. Exit sleep mode (SLP = “0”)
b. Start oscillation
STB: When STB = 1, ILI9325 enters the standby mode and the display operation stops except the GRAM
power supply to reduce the power consumption. In the STB mode, the GRAM data and instructions
cannot be updated except the following two instructions.
a. Exit standby mode (STB = “0”)
b. Start oscillation
DSTB: When DSTB = 1, the ILI9325 enters the deep standby mode. In deep standby mode, the internal logic
power supply is turned off to reduce power consumption. The GRAM data and instruction setting are not
maintained when the ILI9325 enters the deep standby mode, and they must be reset after exiting deep
standby mode.
AP[2:0]: Adjusts the constant current in the operational amplifier circuit in the LCD power supply circuit. The
larger constant current enhances the drivability of the LCD, but it also increases the current
consumption. Adjust the constant current taking the trade-off into account between the display quality
and the current consumption. In no-display period, set AP[2:0] = “000” to halt the operational amplifier
circuits and the step-up circuits to reduce current consumption.

SAP: Source Driver output control
SAP=0, Source driver is disabled.
SAP=1, Source driver is enabled.
When starting the charge-pump of LCD in the Power ON stage, make sure that SAP=0, and set the
SAP=1, after starting up the LCD power supply circuit.
