68 Freescale Semiconductor
5.6 Low-Voltage Detect (LVD) System
The MC9S08EL32 Series and MC9S08SL16 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 a LVD circuit with trip voltages
