6. Registers

The eCPRI IP core registers are 32-bits wide and are accessible to you using the Avalon-MM interface. This table lists the registers available in the IP core. All unlisted locations are reserved.
Table 52.  Register Access Codes
Code Description
RW Read and write
RO Read only
RW1C Read, write, and clear. The user application writes 1 to the register bit(s) to invoke a defined instruction. The IP core clears the bit(s) upon executing instructions.
