hello everyone!

from the link Solved: STM32U5 Can't exit STOP2 mode with LPTIM - STMicroelectronics Community

it is possible to make LPTIM work in stop2

and there is a macro,__HAL_RCC_LPTIMx_CLKAM_ENABLE(), where x can be 1, 3, or 4.

 

but in my project,(STM32Cube_FW_WB_V1.19.0),I can't find this macro

is there anyone who can help me, how to make lptim work and wakeup from stop2

thanks for your help!
