STM32L073 PC13 settings are affecting the LSE oscillation.
We are using STM32L073.When a 512Hz square wave is output to PC1 using LPTIM_OUT (source clock LSE), if the calibration output of PC13 is set to 512Hz, the PC1 output will make a large transition to about 509Hz at around -30 ° C. When set to NONE, th...
