Function
Returns from an exception-handling routine.
Causes a transition to the power-down state.
Rs → CCR, #imm → CCR
Moves immediate data or general register contents to the condition
code register.
CCR → Rd
Copies the condition code register to a specified general register.
CCR ∧ #imm → CCR
Logically ANDs the condition code register with immediate data.
CCR ∨ #imm → CCR
Logically ORs the condition code register with immediate data.
CCR ⊕ #imm → CCR
Logically exclusive-ORs the condition code register with immediate
data.
PC + 2 → PC
Only increments the program counter.
