14.4.10.1 Low-Voltage Interrupt (LVI)
In FPM, VREG_3V3 monitors the input voltage V
status bit LVDS is set to 1. On the other hand, LVDS is reset to 0 when V
interrupt, indicated by flag LVIF = 1, is triggered by any change of the status bit LVDS if interrupt enable
bit LVIE = 1.
14.4.10.2 Autonomous Periodical Interrupt (API)
As soon as the configured timeout period of the API has elapsed, the APIF bit is set. An interrupt, indicated
by flag APIF = 1, is triggered if interrupt enable bit APIE = 1.
Freescale Semiconductor
On entering the Reduced Power Mode, the LVIF is not cleared by the
VREG_3V3.
