A.10 Electrical Specification for Voltage Regulator
A.11 Chip Power-up and Voltage Drops
LVI (low voltage interrupt), POR (power-on reset) and LVRs (low voltage reset) handle chip power-up or
drops of the supply voltage.
Freescale Semiconductor
1. Monitors VDDA, active only in Full Performance Mode. Indicates I/O & ADC performance degradation due to low supply
