Appendix A Instruction Set
A.4
The tables in this section can be used to calculate the number of states required for instruction
execution by the CPU. Table A.5 indicates the number of instruction fetch, data read/write, and
other cycles occurring in each instruction. Table A.4 indicates the number of states required for
each cycle. The number of states required for execution of an instruction can be calculated from
these two tables as follows:
Examples: Advanced mode, program code and stack located in external memory, on-chip
supporting modules accessed in two states with 8-bit bus width, external devices accessed in three
states with one wait state and 16-bit bus width.
