STM8TL52F4P6TR datasheet by STMicroelectronics

STM8TL52F4P6TR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it's recommended to use a maximum of 12 MHz to ensure stability and accuracy.
• How do I configure the watchdog timer to reset the microcontroller?
  To configure the watchdog timer to reset the microcontroller, you need to set the WDPG bit in the WCR register to select the prescaler value, and then set the WDGA bit to enable the watchdog timer. You can also use the IWDG (Independent Watchdog) to reset the microcontroller.
• Can I use the UART in synchronous mode?
  No, the UART in the STM8TL52F4P6TR does not support synchronous mode. It only supports asynchronous mode.
• How do I enable the internal pull-up resistors on the GPIO pins?
  To enable the internal pull-up resistors on the GPIO pins, you need to set the corresponding bit in the PUPR register. For example, to enable the pull-up resistor on port A, you would set the PA_PUPR bit in the PUPR register.
• What is the minimum voltage required to program the microcontroller using the SWIM interface?
  The minimum voltage required to program the microcontroller using the SWIM interface is 2.7V.
