3.10 Graphics Connectors or GFX Card Interface (J910)
The PIC32-BZ6 Curiosity Board is designed to have a modular
graphics interface. This interface enables the use of several different graphics cards,
which allows for expandability and different use cases. AC42G34A 24-bit to 8-bit pass though card is required with
the kit , this board passes parallel data through, and can be configured to an 8-bit LCC
mode. For the pin description, refer to the following table.
