Function
Starts trap-instruction exception handling
Returns from an exception-handling routine
Causes a transition to the power-down state
(EAs) → CCR
Moves the source operand contents to the condition code register.
The condition code register size is one byte, but in transfer from
memory, data is read by word access.
CCR → (EAd)
Transfers the CCR contents to a destination location. The condition
code register size is one byte, but in transfer to memory, data is
written by word access.
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.
