hello, please tell me more~ how's it work ?

eg) st7lite05 have LVD (3 level), what is the meanning ?

is it the MCU will interrupt when the battery reach 4.5V, 3V, 1.5V ?

Or is it a word memory record the now battery status? we can read it out any time ? is it the LVD use and I/O port ? or it can detect at the pin (VDD) ?

THANK YOU VERY MUCH

hello,

The job of the LVD is to monitor VDD and generate a reset when the operating supply is too low. You can use Lite0 A/D converter to monitor an I/O pin or check battery status

hope this helps
