The MC9S08QD4 series includes a system to protect against low voltage conditions in order to protect
memory contents and control MCU system states during supply voltage variations. The system is
comprised of a power-on reset (POR) circuit and an LVD circuit with a user selectable trip voltage, either
high (V
voltage is selected by LVDV in SPMSC2. The LVD is disabled upon entering any of the stop modes unless
LVDSE is set in SPMSC1. If LVDSE and LVDE are both set, then the MCU cannot enter stop1 or stop2,
and the current consumption in stop3 with the LVD enabled will be greater.
