APPENDIX A Instruction Lists
Notes:
• In the "ADD SP" instruction, the field "s8" in the TYPE-D instruction format has the following
relation to the value "s10" in assembly notation.
s10
→ s8=s10 >> 2
• In the "ENTER" instruction, the field "u8" in the TYPE-D instruction format has the following
relation to the value "u10" in assembly notation.
u10
→ u8=u10 >> 2
• The number of execution cycles for the "LDM0" (reglist) and "LDM1" (reglist) instructions is:
a × (n – 1) + b + 1 cycles, where "n" is the number of registers designated.
• The number of execution cycles for the "STM0" (reglist) and "STM1" (reglist) instructions is:
a × n+1 cycles, where "n" is the number of registers designated.
