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.
| 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. |
| control_write | 1 | Input | |
| control_byteenable | 4 | Input | |
| control_writedata | 32 | Input | |
| control_read | 1 | Input | |
| control_readdata | 32 | Output | |
| control_readdatavalid | 1 | Output | |
| control_waitrequest | 1 | Output | |
| control_irq | 1 | Output | Active high interrupt signal. |
