2.2.1 Read Operation

Read operations are independent of write operations and are performed asynchronously. Synchronous read operations can be performed by using fabric flip-flops as pipeline registers. These flip-flops are located in the associated interface cluster at the read address input and read data output.

When the input address (R_ADDR[]) is provided, the output data is available on the output data bus. When BLK_EN is high, the read operations are enabled. R_DATA contains the contents of the memory location selected by R_ADDR. When BLK_EN is low, the R_DATA is driven to zero.

The following figure shows the timing of read operation.
