1
The n is the number of registers moved by the MOVEM opcode.
2
If a MOVE.W #imm,SR instruction is executed and imm[13] equals 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).
