The D/A converted 64 gray scale analog voltage is output.
The display data is input with a width of 18 bits,
gray-scale data (6 bits) by 3 dots (R,G,B) DX0: LSB, DX5: MSB
This pin controls the direction of shift register in cascade connection.
The shift direction of the shift registers is as follows.
SHL = H: DIO1 input, Y1
→
Y309, DIO2 output
SHL = L: DIO2 input, Y309
→
Y1, DIO1 output
SHL = H: Used as the start pulse input pin.
SHL = L: Used as the start pulse output pin.
SHL = H: Used as the start pulse output pin.
SHL = L: Used as the start pulse input pin.
Refer to the shift register's shift clock input. the display data is loaded
to the data register at the rising edge of CLK2.
Latches the contents of the data register at rising edge and transfers
them to the D/A converter. Also, after CLK1 input, clears the internal
shift register contents. After 1 pulse input on start, operates normally.
CLK1 input timing refers to the "Relationships between CLK1 start
pulse (DIO1, DIO2) and blanking period" of the switching
characteristic waveform.
This pin controls 300CH or 309CH output.
SELT = H: 309CH output
→
Y151 to Y159 are useless.
SELT = L: 300CH output.
→
Y151 to Y159 are useless.
This pin is internally pulled-up.(Rpu = 30 k

Keep gray-scale power supply unchanged during the gray-scale
voltage output.
