STM8S207R8T6CTR datasheet by STMicroelectronics

STM8S207R8T6CTR 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 (WDT) to reset the microcontroller?
  To configure the WDT to reset the microcontroller, you need to set the WDT prescaler and counter values using the WDT_CR and WDT_R registers, and then enable the WDT by setting the WDTE bit in the WDT_CR register.
• Can I use the UART peripheral in asynchronous mode with a baud rate higher than 115200 bps?
  No, the UART peripheral in asynchronous mode is limited to a maximum baud rate of 115200 bps. For higher baud rates, you need to use synchronous mode or an external UART module.
• How do I enable the brown-out reset (BOR) feature?
  To enable the BOR feature, you need to set the BOREN bit in the RCC_CSR register and configure the voltage threshold using the BORV bits in the RCC_CSR register.
• What is the minimum voltage required for the microcontroller to operate correctly?
  The minimum voltage required for the STM8S207R8T6CTR to operate correctly is 2.95V, but it's recommended to use a minimum voltage of 3.0V to ensure reliable operation.
