Instruction Timing
2.7.5 Branch Instruction Execution Times
Table 2-16 shows general branch instruction timing.
1
For the conditional branch opcodes (bcc), a static algorithm is used to determine the
prediction state of the branch. This algorithm is:
if bcc is a forward branch && CCR[7] == 0

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