DISPB_D3_DATA
DISPB_D3_DRDY
DISPB_D3_CLK latches data into the panel on its negative edge (when positive polarity is
selected). In active mode, DISPB_D3_CLK runs continuously.
DISPB_D3_HSYNC causes the panel to start a new line.
DISPB_D3_VSYNC causes the panel to start a new frame. It always encompasses at least one
HSYNC pulse.
DISPB_D3_DRDY acts like an output enable signal to the CRT display. This output enables the
data to be shifted to the display. When disabled, the data is invalid and the trace is off.
DISPB_D3_CLK
depicts the LCD interface timing for a generic active matrix color TFT panel. In this figure,
depicts the horizontal timing (timing of one line), including both the horizontal sync pulse and
Synchronous Interfaces
