Multiplexed data - two 24-bit words per pixel from both D1[11:0] and D2[11:0]
Clock frequency equals 1/2X pixel rate with 24-bit data transfer at both rising and falling clock edges.
Maximum pixel rate is 330M pixels per second with a 165 MHz pixel clock.
No Simultaneous TV and panel display.
Non-multiplexed data - one 24-bit word per pixel from both D1[11:0] and D2[11:0].
Clock frequency equals 1X pixel rate with 24-bit data transfer at either rising or falling edge of clock
(programmable via serial port).
Maximum pixel rate is 330M pixels per second with a 330 MHz pixel clock.
No simultaneous TV and panel display.
