Table 21 Branch 2 [20 Instructions]
Note: For (a) to (d), refer to “Table 4 Number of Execution Cycles in Addressing Modes” and “Table 5 Correction
Values for Number of Cycles for Calculating Actual Number of Cycles.”
*1: Set to 4 when branch is executed, and 3 when branch is not executed.
*2: Set to 5 when branch is executed, and 4 when branch is not executed.
*3: Set to 5 + (a) when branch is executed, and 4 + (a) when branch is not executed.
*4: Set to 6 + (a) when branch is executed, and 5 + (a) when branch is not executed.
*5: Set to 3

(c) when an interrupt request is issued, and 6
×
(c) for return.
*6: This is a high-speed interrupt return instruction. In the instruction, an interrupt request is detected. When an
interrupt occurs, stack operation is not performed, with this instruction branching to the interrupt vector.
*7: Return from stack (word).
*8: Return from stack (long).
