I have a question about a signal (Interrupt signal) in the STM reference manual RM0433. On Page 697 , table 125 the Trigger input 14 is named "Lptim5_ait". I cant find any reference for this signal.

I'm trying to set up a BDMA Stream with Lptim5 as trigger source. Which interrupt on the Lptim5 can i use? "Lptim5_ait" is not listed as an interrupt in the Lptim section of the manual ( page 1881, table 350).

Happy new year and thanks in advance!

​Hello @Willi Färber​,

lptim_ait is the lptim asynchronous interrupt or what we can call wakeup signal.

​it is equivalent to synchronous IT (but mainly used to wakeup the system where all clocks are off).
