MCF51AC128ACFUE datasheet by Freescale Semiconductor

MCF51AC128ACFUE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MCF51AC128ACFUE?
  The maximum clock frequency of the MCF51AC128ACFUE is 50 MHz.
• How do I configure the clock source for the MCF51AC128ACFUE?
  The clock source for the MCF51AC128ACFUE 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 source, external clock source, or the crystal oscillator.
• What is the purpose of the COP (Computer Operating Properly) timer in the MCF51AC128ACFUE?
  The COP timer is a watchdog timer that resets the microcontroller if it does not receive a refresh signal within a certain time period. This is used to prevent the microcontroller from getting stuck in an infinite loop or malfunctioning due to software errors.
• How do I use the ADC (Analog-to-Digital Converter) in the MCF51AC128ACFUE?
  The ADC in the MCF51AC128ACFUE can be used by configuring the ADC control registers, selecting the analog input channel, and starting the conversion process. The converted digital value can then be read from the ADC result registers.
• What is the maximum amount of flash memory that can be programmed in the MCF51AC128ACFUE?
  The MCF51AC128ACFUE has 128 KB of flash memory, and the maximum amount of flash memory that can be programmed is 128 KB - 4 KB (reserved for the bootloader) = 124 KB.
