Note : The 4250 Group just invalidates the next instruction when a skip is performed. The contents of program counter is not
increased by 2. Accordingly, 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.
