MC9S08AC8CFGE datasheet by Freescale Semiconductor

MC9S08AC8CFGE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MC9S08AC8CFGE?
  The maximum clock frequency of the MC9S08AC8CFGE is 20 MHz.
• How do I configure the internal clock oscillator?
  The internal clock oscillator can be configured using the CLKSEL register. The CLKSEL register is used to select the clock source and configure the clock frequency.
• What is the purpose of the COP (Computer Operating Properly) module?
  The COP module is a watchdog timer that monitors the operation of the microcontroller. It resets the microcontroller if it detects a fault or if the software fails to refresh the COP timer within a specified time period.
• How do I use the ADC (Analog-to-Digital Converter) module?
  The ADC module can be used to convert analog signals to digital values. The ADC module is configured using the ADCSC1 and ADCSC2 registers. The ADC conversion result is stored in 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.
