Instruction Size^* Function
TRAPA
—
Starts trap-instruction exception handling.
RTE
—
Returns from an exception-handling routine.
SLEEP
—
Causes a transition to a power-down state.
LDC
B/W (EAs) → CCR, (EAs) → EXR
Moves the source operand contents or immediate data to CCR or EXR.
Although CCR and EXR are 8-bit registers, word-size transfers are
performed between them and memory. The upper 8 bits are valid.
STC
B/W CCR → (EAd), EXR → (EAd)
Transfers CCR or EXR contents to a general register or memory.
Although CCR and EXR are 8-bit registers, word-size transfers are
performed between them and memory. The upper 8 bits are valid.
ANDC
B
CCR ∧ #IMM → CCR, EXR ∧ #IMM → EXR
Logically ANDs the CCR or EXR contents with immediate data.
ORC
B
CCR ∨ #IMM → CCR, EXR ∨ #IMM → EXR
Logically ORs the CCR or EXR contents with immediate data.
XORC
B
CCR ⊕ #IMM → CCR, EXR ⊕ #IMM → EXR
Logically XORs the CCR or EXR contents with immediate data.
NOP
—
PC + 2 → PC
Only increments the program counter.
Note: * Refers to the operand size.
B: Byte
W: Word
L: Longword
