I really think the image is misleading because the sixth step should be "MDR contents to CIR" (as MAR is an adresse and MDR is the Data just read from memory).
Just picked this up in 2018 - it doesn't look like this error is getting corrected anytime soon...still, it makes a useful exercise to check to see if my students understand the cycle.Lessentropy (talk) 20:20, 21 March 2018 (UTC)
