33 bool "LSE"35 Use LSE as LPTIM clock56 - LSE(32678): 4096 ticks/sec
25 - Clocked by an oscillator available in Stop mode (LSE, LSI) or an oscillator capable28 - If LSE is selected as clock source and shell serial port is a LPUART current speed82 - Chose LSE as clock source
36 After flashing, the LSE clock will be output on the MCO pin enabled in Device Tree.
