Note :The 4513/4514 Group just invalidates the next instruction when a skip is performed. The contents of program counter is not increased by 2. Accord-
ingly, the number of cycles does not change even if skip is not performed. However, the cycle count becomes “1” if the TABP p, RT, or RTS instruction
is skipped.
