Q Cycle Activity
Tosc
Each instruction cycle (Tcy) is comprised of four Q cycles (Q1-Q4). The Q cycle is the same as
the device oscillator cycle (T
Read, Process Data, Write etc., of each instruction cycle. The following diagram shows the rela-
tionship of the Q cycles to the instruction cycle.
The four Q cycles that make up an instruction cycle (Tcy) can be generalized as:
Each instruction will show the detailed Q cycle operation for the instruction.
