RL78/I1D
Operation State Switching IAR
Summary
The application note shows the register setting sequence for the switch of RL78/I1D operation state, using the
Operation State Control. After reset, it operates in the LV mode. The flash operation mode is switched one by one by
the button pressing (LV mode → LS mode → HS mode → LS mode → LP mode → LS mode →LV mode, repetition at
the following). The power-supply voltage VDD should be confirmed with the A/D converter when switching to the HS
mode, and if the voltage is out of specified range, the transition should be avoided.
