Hi, Found a bug in recent mbed5.12 & 5.13, as compiled a sampled template STM32_READ_ANALOG to run on STM32L432KC

The SW is to read the analog value from pin A4

I have attached the serial console captured shown that upper section readings (wrong readings) are based on mbed5.13 (similar result as for mbed5.12) and the lower readings are sw compiled from mbed5.11 that give the correct readings.
