The data flow that will produce the maximum response time is shown below. De-
lays over the minimum response time occur because the input to be transferred
through the host computer is received immediately following the I/O refresh peri-
od (requiring a wait to the next cycle) and because the command from the host
computer to write the bit to be output from PC for Unit #31 is received immediate-
ly following host link servicing (again requiring a wait to the next cycle). The
equation for the maximum response time is given below the diagram.
