Resets, Interrupts, and System Configuration
5.6
The MC9S08RC/RD/RE/RG 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, an LVD circuit with flag bits for warning and detection, and
a mechanism for entering a system safe state following an LVD interrupt. The LVD circuit can be
configured to generate an interrupt or a reset when low supply voltage has been detected.
