Function

67 to 50 I/O These pins comprise 18-bit bi-directional data.

When the chip is not selected, D0 to D17 are in high impedance mode.

71

Input When parallel data transfer has been selected, this pin is usually

connected to the least significant bit of the standard CPU address bus and

is used to distinguish between data from display data and commands.

RS = H: Indicates that data from D0 to D17 is display data.

RS = L: Indicates that data from D0 to D17 is commands.

84

Input When parallel data transfer has been selected, this pin is selected data

major selection that inputs display data through serial interface.

DTX = H: 1-pixel/18-bit mode

DTX = L: 1-pixel/16-bit mode

43

Input This pin is for oscillation signal selection. When is used external resistance

connected oscillation circuit, this pin sets H. When in used CR internal

oscillation circuit, this pin sets L.

OSCSEL = H: External resistance connected oscillation circuit select

OSCSEL = L: CR internal oscillation circuit select

47

Input This pin is for oscillation signal input.

OSCSEL = H: Connect 42 kΩ resistance between OSCIN and OSCOUT.

(240 line, in case of NGO = 0)

OSCSEL = L: Leave it open.

45

Output This pin is for oscillation signal input.

OSCSEL = H: Connect 42 kΩ resistance between OSCIN and OSCOUT.

(240 line, in case of NGO = 0)

OSCSEL = L: Leave it open.

49

Output This pin outputs STB signal for gate driver leveled by interface power

supply voltage (VDD1). This output signal is reverse signal of GSTB.

Output

This is a general-purpose output port. The status of these pins (H or L) can

be write via a command.

Leave open when in unused.
