1.3.6.1.2. Control Status Register Read Operation

To execute the read operation for the control status register, perform the following steps:

  1. Asserts avl_csr_read high.
  2. Write a correct address of the register in the avl_csr_address bus. Refer to the Register Map for register information.
  3. Wait for the avl_csr_readdata_valid signal to go high.
  4. Retrieve read data from avl_csr_readdata.
