FUNCTION
Used as power supply pin for digital circuit, connected to +2.7 to +3.6 V.
Used as power supply pin for analog circuit, connected to +8.0 to +12.0 V.
Used as ground pin, connected to 0 V.
Used as input pins of start pulse and also used as output pins for cascade connection.
When "H" is input into start pulse input pin, data sampling is started. On completion of
sampling, "H" pulse is output to output pin for cascade connection. Pin functions are
selected by LBR. For selecting, refer to "Functional Operations".
Used as input pin for selecting the shift register direction. For selecting, refer to
"Functional Operations".
Used as input pin for parallel transfer from sampling memory to hold memory. Data is
transferred at the rising edge and output from LCD drive output pin.
Used as shift clock input pin. Data is latched into sampling memory from data input pin at
the rising edge.
Used as reference voltage input pins. Hold the reference voltage fixed during the period of
LCD drive output. For relation between input data and output voltage values, refer to
"Output Voltage Value". For internal gamma correction, refer to "Gamma Correction
Value". Observe the following relation for input voltage.
VLS > VH0 ≥ VH8 ≥ π ≥ VH63 ≥ VL63 ≥ VL56 ≥ π ≥ VL0 > GND.
Used as data input pins of R, G, and B colors. 6-bit data are input from data pins at the
rising edge of CK. When PBS is "L", 2-pixel data are input from XA0 to XA5, YA0 to YA5,
ZA0 to ZA5 and XB0 to XB5, YB0 to YB5, ZB0 to ZB5 at the same time.
When PBS is "H", 1-pixel data is input from XA0 to XA5, YA0 to YA5 and ZA0 to ZA5, and
fixed XB0 to XB5, YB0 to YB5 and ZB0 to ZB5 to "L" or "H". For relation between input data
and output voltage values, refer to "Functional Operations" and "Output Voltage Value".
Select the data to be entered into X, Y, and Z according to picture element arrays of the
panel.
Used as input pin for selecting the number of LCD drive outputs, which sets up operation
mode with PBS pin. When "L" is entered, it becomes 324-output/2-port input mode at PBS
pin "L" or 321-output/1-port input mode at PBS pin "H". When "H" is entered, it becomes
312-output/2-port input mode at PBS pin "L" or 309-output/1-port mode at PBS pin "H". For
selecting the number of LCD drive outputs, refer to "Output Characteristics".
Used as 2-port/1-port exchange input pin to take in data. When "L" is entered, it becomes
2-port input mode and 2-pixel data are input at the same time. When "H" is entered, it
becomes 1-port input mode.
