Draw time diagram for memory read operation
WebThe opcode fetch and read cycles are similar. Hence the timing diagram can be categorized in two parts, the first is the timing diagram for read cycle and the second is the timing diagram for write cycle. The read cycle begins in T1 with the assertion of address latch enable (ALE) signal and also M / IO signal. During the negative going edge of http://bittpolytechnic.com/images/pdf2/ECE_Lecture%20notes%20DTM%204th%20semester%20(3).pdf
