Descriptions
RSDS^TM input terminals of display data
Differential The 3-bit differential input pairs generate the internal 6-bit data through the
comparison between D_XXP and D_XXN.
Differential
The RSDS^TM clock input pair generate the internal shift clock through the
comparison between CLK_P and CLK_N.

Driver outputs for D/A converted 64 gray scale analog voltage.
The shift direction of internal shift register is controlled by this pin as shown below.

The data in the data register are transferred to the data latch at the rising edge of STB,
then the gray scale voltages are output from the buffer at the falling edge of STB.
