Programming.
→ALUi1, instruct ALU to decrement ALUo →Z, ALUo →MARDM, Rr →DM STS k,Rr Store 8-bit register Rr at address k. The address uses a second 16-bit program memory word. We apply the same “mini-fetch” within the execution phase as discussed for LDS Rd,k. loadPC kept high, loadNPC also, modeNPC=1
