In the ML62Q1000 series, the microcontroller cannot be completely reset by software alone. After resetting with the BRK instruction, there is a method to initialize the peripheral circuit by using BRECON 0 to 3 reset or SOFTRCON reset. Alternatively, although it may take some time, you can reset it by overflowing the watchdog timer.
