Instruction Cycle Lengths
Table 6: Instruction Cycle Lengths
Note: The specific timing requirements for Short, Medium, and Long cycles are given in the Switching Characteristics section under the
tELEH parameter. For two cycle Command Writes (TCO reg or any instruction with “aaaH” as the source or destination), the first
cycle is short, and the second cycle is the length given.
