4.1.3. Avalon Memory-Mapped Interface Control Signals

The Avalon Memory-Mapped agent control interface provides access to the control and status registers in the MIPI DSI-2 IP and CVO subcore to a host processor

This interface operates on the same clock domain as the Altera Streaming Video input on the MIPI DSI-2 IP.

For details on the register map, see Appendix B: Registers.
Table 22.  Avalon Memory-Mapped Interface Control Signals
Signal Name Width Direction Description
control_address 10 Input

Standard Avalon® memory-mapped interface, supporting transfers in burst mode with full handshaking.

Write transfers always have a wait time of 0 cycle while read transfers have a wait time of 1 cycle. The interface should be accessed using word addressing in the Platform Designer flow. For example, an address of 4 in the Nios® V software selects the address of 1 in the agent.
