This document details the definitions and procedures for the Read and Write Cycles in digital clock signal testing. It outlines the specific steps for the read cycle, including changing the address, asserting control signals, waiting for data output, and verifying the output data. Similarly, it describes the write cycle process, highlighting changes to the address and data input, along with the assertion of control signals. These guidelines are crucial for effective testing and validation of digital clock components in embedded systems. ###
