MC9S08JM32CGT Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MC9S08JM32CGT?
  The maximum clock frequency of the MC9S08JM32CGT is 20 MHz, but it can be overclocked to 24 MHz with reduced voltage and temperature range.
• How do I configure the internal oscillator on the MC9S08JM32CGT?
  The internal oscillator on the MC9S08JM32CGT can be configured using the OSCCLK register. The oscillator frequency can be set to 4 MHz, 8 MHz, or 16 MHz by writing the appropriate values to the OSCCLK register.
• What is the purpose of the VLLS (Very Low Leakage Stop) mode on the MC9S08JM32CGT?
  The VLLS mode on the MC9S08JM32CGT is a low-power mode that reduces the power consumption of the device to a minimum. In VLLS mode, the device consumes only 0.2 μA of current, making it suitable for battery-powered applications.
• How do I use the ADC on the MC9S08JM32CGT?
  The ADC on the MC9S08JM32CGT can be used by configuring the ADCSC1 and ADCSC2 registers. The ADC clock speed, conversion mode, and channel selection can be set using these registers. The ADC result can be read from the ADCRH and ADCRL registers.
• What is the maximum current that can be sourced or sunk by the GPIO pins on the MC9S08JM32CGT?
  The maximum current that can be sourced or sunk by the GPIO pins on the MC9S08JM32CGT is 25 mA. However, the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
