Miscellaneous Instruction Execution Times

Table 2-14. Two Operand Instruction Execution Times (continued)
Opcode <EA>
subi.l #imm,Dx
subq.l #imm,<ea>
subx.l Dy,Dx
1
For divide and remainder instructions the times listed represent the worst-case timing. Depending on the operand
values, the actual execution time may be less.

1
n is the number of registers moved by the MOVEM opcode.
2
If a MOVE.W #imm,SR instruction is executed and imm[13] = 1, the execution time is 1(0/0).
3
The execution time for STOP is the time required until the processor begins sampling continuously for interrupts.
4
PEA execution times are the same for (d16,PC).
5
PEA execution times are the same for (d8,PC,Xn*SF).
