Question 1: Is there any penalty or bandwidth constraint between Display Controller 0 and Display Controller 1 in the graphics subsystem of Traveo™ S6J3200 MCU? Answer 1: There is no constraint from the software and graphics point of view. However, there are differences between the physical pins on the MCU. Display Controller 0 can drive higher pixel clock (80 MHz) compared to Display Controller 1 (50 MHz). Also, Display Controller 0 pins have higher drive strength.
Question 2: Can Display Controller 0 and Display Controller 1 support DRGB888, RSDS, and LVDS formats? Answer 2: Display Controller 0 supports RSDS, DRGB, and LVDS for some part number options. Display Controller 1 supports only DRGB. For more detail, see Chapter 2.2 Optional Function of the S6J3200 Series Datasheet.
Question 3: Does the graphics subsystem of Traveo S6J3200 MCU support PNG decompression? Answer 3: No, the graphics subsystem of Traveo S6J3200 MCU does not support PNG decompression.
Question 4: What happens when an unlock function of graphics subsystem is executed more than 15 times? Answer 4: If an unlock function of graphics subsystem is executed more than 15 times, NMI 20 ‘Graphics subsystem memory protection’ occurs.
Question 5: How can I setup 8 or 16 scanlines mode of 3D Graphics Core? Answer 5: 3D Graphics driver software supports only four scanlines mode. User applications cannot change the scanline setting.
