B Instruction Execution Time
B-6 Execution Time on Combination of Applicable Devices and Indexing
Appendix B-6 Execution Time on Combination of Applicable Devices and
Indexing
In examples shown below for basic instructions, MOV instruction and data comparison instructions, the
instruction execution time varies depending on the combination of target devices and absence/presence of
indexing.
The combinations of target devices marked with "*1" and "*2" are handled as exceptions because high speed
processing is adopted in the technique.
Appendix B-6-1 Basic instruction (LD/LDI/AND/ANI/OR/ORI) execution time
Appendix B-6-2 Applied instruction execution time
1. MOV (FNC 12) instruction execution time
MOV instruction (16-bit operation)
*1. *2. These combinations are handled as exceptions because high speed processing is adopted in the
technique.
DMOV instruction (32-bit instruction)
*1. *2. These combinations are handled as exceptions because high speed processing is adopted in
the technique.
