SECTION 6
Program Execution Timing
The timing of various operations must be considered both when writing and debugging a program. The time required to ex-
ecute the program and perform other CPU operations is important, as is the timing of each signal coming into and leaving the
PC in order to achieve the desired control action at the right time. This section explains the cycle and shows how to calculate
the cycle time and I/O response times.
