ST10F168-Q3 datasheet by STMicroelectronics

ST10F168-Q3 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. However, it's recommended to use a clock frequency of 12 MHz or lower to ensure reliable operation.
• How do I configure the watchdog timer?
  The watchdog timer can be configured using the WDTCSR register. Set the WDTON bit to enable the watchdog timer, and set the WDP bits to select the timeout period. The watchdog timer can be reset using the WDR instruction.
• What is the purpose of the BOD (Brown-Out Detector) and how do I use it?
  The BOD is used to detect when the voltage supply drops below a certain threshold. It can be enabled by setting the BODEN bit in the MCUCR register. The BOD threshold voltage can be selected using the BODLEVEL bits in the MCUCR register.
• How do I use the analog-to-digital converter (ADC) on the ST10F168-Q3?
  The ADC can be used by setting the ADMUX register to select the analog input channel, and then starting the conversion by setting the ADSC bit in the ADCSRA register. The conversion result can be read from the ADCL and ADCH registers.
• What is the maximum current that can be sourced or sunk by the I/O pins?
  The maximum current that can be sourced or sunk by the I/O pins is 20 mA. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation.
