Table 4
Number of Execution Cycles for Effective Address in Addressing Modes
Note: (a) is used for ~ (number of cycles) and B (correction value) detailed instruction rules in instruction table.
Table 5
Correction Value for Number of Cycles for Calculating Actual Number of Cycles
Notes: (b), (c), (d) is used for ~ (number of cycles) and B (correction value) in instruction table.
When the external bus is used, cycles for wait insertion for the ready input and automatic ready operation
must be added.
Table 6
Correction Value for Number of Cycles for Calculating Number of Program Fetch Cycles
Notes: When the external bus is used, cycles for wait insertion for the ready input and automatic ready operation
must be added.
Because execution of instruction is not delayed for all program fetch operations, use this value to calculate
the worst case.
