The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it depends on the voltage and temperature range. Refer to the datasheet for more information on the oscillator frequency ranges.
To configure the WDT, you need to set the WDP bits in the WDT control register (WDT_CR) to select the timeout period, and then enable the WDT by setting the WDTE bit. Make sure to follow the correct sequence to avoid accidental resets.
Yes, the UART in the STM8L101G2U6A can be used in asynchronous mode with a baud rate generator. You need to configure the UART clock, set the baud rate, and enable the UART transmitter and receiver.
To use the internal temperature sensor, you need to enable the temperature sensor by setting the TSEN bit in the ADC control register (ADC_CR1). Then, configure the ADC to read the temperature sensor channel, and convert the reading to a temperature value using the formula provided in the datasheet.
The minimum voltage required for the STM8L101G2U6A to operate is 1.8V, but it depends on the frequency and temperature range. Refer to the datasheet for more information on the operating voltage ranges.
