6.1. CSI-2 Receiver Register Map

Base address (control_address[9:8]) 0x0 accesses the MIPI CSI-2 receiver control and status registers. Base 0x1 accesses the CV2AXI registers.
Table 26.  Register Access Codes
Code Description
RW Read and write.
RO Read only.
RW1C Read, write and clear. Your application writes 1 to the register bit(s) to invoke a defined instruction. The IP clears the bit(s) on running instructions.
