MCF51AG128CLH Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the MCF51AG128CLH?
  The maximum clock frequency for the MCF51AG128CLH is 50 MHz, but it can be overclocked to 60 MHz with reduced voltage and temperature ranges.
• How do I configure the internal oscillator on the MCF51AG128CLH?
  The internal oscillator on the MCF51AG128CLH can be configured using the OSCCLKSEL register. The oscillator frequency can be set to 31.25 kHz, 4 MHz, or 8 MHz, and the clock source can be selected as either the internal oscillator or an external clock source.
• What is the maximum amount of current that can be sourced or sunk by the GPIO pins on the MCF51AG128CLH?
  The maximum amount of current that can be sourced or sunk by the GPIO pins on the MCF51AG128CLH is 25 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
• How do I implement a watchdog timer on the MCF51AG128CLH?
  The MCF51AG128CLH has a built-in watchdog timer that can be enabled and configured using the COPCTL register. The watchdog timer can be set to timeout after a specified period of time, and can be reset using the COPRST register.
• What is the minimum voltage required for the MCF51AG128CLH to operate?
  The minimum voltage required for the MCF51AG128CLH to operate is 2.7V, but it is recommended to operate the device at a voltage of 3.0V or higher for optimal performance and reliability.
