MCF51AC256BCLKE datasheet by Freescale Semiconductor

MCF51AC256BCLKE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MCF51AC256BCLKE?
  The maximum clock frequency of the MCF51AC256BCLKE is 50 MHz.
• How do I configure the clock source for the MCF51AC256BCLKE?
  The clock source for the MCF51AC256BCLKE can be configured using the SYNR and REFS bits in the System Options Register (SOR). The clock source can be set to either the internal clock, external clock, or the crystal oscillator.
• What is the purpose of the Low-Voltage Detect (LVD) module in the MCF51AC256BCLKE?
  The Low-Voltage Detect (LVD) module in the MCF51AC256BCLKE is used to monitor the voltage level of the power supply and generate a reset signal if the voltage falls below a certain threshold. This helps to prevent the microcontroller from operating in an unstable condition.
• How do I use the ADC module in the MCF51AC256BCLKE?
  The ADC module in the MCF51AC256BCLKE can be used to convert analog signals to digital signals. The ADC module is configured using the ADC Control Register (ADCCFG) and the ADC Status Register (ADCSTAT). The ADC module can be triggered using the ADC Trigger Register (ADCTRG).
• What is the purpose of the Watchdog Timer (WDT) in the MCF51AC256BCLKE?
  The Watchdog Timer (WDT) in the MCF51AC256BCLKE is used to prevent the microcontroller from getting stuck in an infinite loop or a deadlock situation. The WDT generates a reset signal if the microcontroller does not refresh the WDT counter within a certain time period.
