MC9S08AW60CFDE datasheet by Freescale Semiconductor

MC9S08AW60CFDE Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MC9S08AW60CFDE?
  The maximum operating frequency of the MC9S08AW60CFDE is 20 MHz, but it can be overclocked to 24 MHz with some limitations.
• How do I configure the internal clock source?
  The internal clock source can be configured using the SYNR and REFS registers. The SYNR register sets the clock source, and the REFS register sets the clock frequency.
• What is the purpose of the COP (Computer Operating Properly) module?
  The COP module is a watchdog timer that resets the microcontroller if it fails to respond within a specified time period, ensuring that the system remains operational and preventing lockups or hangs.
• How do I use the ADC (Analog-to-Digital Converter) module?
  The ADC module can be used by configuring the ADCSC1 and ADCSC2 registers to select the channel, resolution, and conversion mode. 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?
  The maximum current that can be sourced or sunk by the GPIO pins is 25 mA, but it's recommended to limit the current to 10 mA to ensure reliable operation.
