• Manufacturer: Freescale Semiconductor, Inc

17.4.11.1 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.
17.4.11.2 HTI - High Temperature Interrupt
In FPM VREG monitors the die temperature T
HTDS is set to 1. Vice versa, HTDS is reset to 0 when T
by flag HTIF=1, is triggered by any change of the status bit HTDS if interrupt enable bit HTIE=1.
17.4.11.3 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.
On entering the Reduced Power Mode the HTIF is not cleared by the VREG.
