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