wb55 can't wakeup from stop2 by LPTIM
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!
