5. Please note that this “Read Operation” will not

result in placing the contents of a QUART register on the

data bus. The only thing that will happen, in response to

this procedure is the Counter/Timer #1 will initiate

counting. For a detailed discussion into the operation of

the Counter/Timers, please see Section D.2.
