Table 2.8 System Control Instructions
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
Moves the source operand contents to the CCR. The CCR size is one
byte, but in transfer from memory, data is read by word access.
STC
B/W 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.
ANDC
B
CCR ∧ #IMM → CCR
Logically ANDs the CCR with immediate data.
ORC
B
CCR ∨ #IMM → CCR
Logically ORs the CCR with immediate data.
XORC
B
CCR ⊕ #IMM → CCR
Logically XORs the CCR with immediate data.
NOP
—
PC + 2 → PC
Only increments the program counter.
Note: * Refers to the operand size.
B: Byte
W: Word
