The Video Timing Controller (VTC) core uses the AXI4-Lite industry standard control interface to connect to other system components. The following sections describe the various interfaces available with the core. Some signals are optional and not present for all configurations of the core. The AXI4-Lite interface and the IRQ pin are present only when the core is configured via the GUI with an AXI4-Lite control interface. The INTC_IF interface is present only when the core is configured via the GUI with the INTC interface enabled. This Figure illustrates an I/O diagram of the VTC core.
