BIT4 = 0Î The parallel mode is use 8-bit data bus.

BIT4 = 1Î The parallel mode is use 4-bit data bus (Default).

This pin must be kept high for serial mode.

Parallel/Serial Select

I

P/ S = 0 Î The MPU interface is serial mode (Default). See the setting of

Voltage Source of LCD Driver

O

The relationship of the power is VOUT>V0≧V1≧V2≧V3≧V4≧VSS

Capacitor Input

I These are used to connect capacitors for internal Booster.

O Booster Output

Reference Voltage Input

I

This is the external reference voltage input when the internal one is

disabled.

Voltage Adjustment

I

Applies voltage between V0 and VSS by connecting a resistor divider.

Clock Select

I

This pin is used to select the clock source. When CLK_SEL is “1”, the

clock is generated by internal RC oscillator. When CLK_SEL is “0”, the

system clock is driven by external pin - EXT_CLK.

External Clock

I When CLK_SEL is “0”, this pin is the external clock input. When CLK_SEL

is “1”, this pin is not used and has to be connected to VDD or GND.
