Cascading LPTIM in STM32WL55JC17

Associate II

I'd like to know if it is possible to cascade two LPTIM in order to make a 32-bit counter. I'm implementing my main LoRa application with the sequencer but I need to have 32-bit hardware counter running continously in the background to count external pulses. If it is not possible to use LPTIM's in this configuration, is there a way to configure TIM2 (a 32-bit timer) to keep running in low power mode?

Hello @JPablo1 and welcome to ST Community.

You can cascade two LPTIM. To do the job you have to take a look to the chapter 28 and the part 12.3.2 of the Reference Manual RM0453.
