MC9S12GC64CFUE datasheet by Freescale Semiconductor

MC9S12GC64CFUE Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The MC9S12GC64CFUE can operate from -40°C to 125°C, but the recommended operating temperature range is -40°C to 105°C.
• How do I configure the clock settings for this microcontroller?
  The clock settings can be configured using the Clock Generation Module (CGM) registers. The CGM provides a flexible clock system that allows the user to select from various clock sources, including the internal oscillator, external oscillator, and PLL.
• What is the maximum frequency of the CPU and peripherals?
  The maximum frequency of the CPU is 25 MHz, and the maximum frequency of the peripherals is 50 MHz.
• How do I use the ADC module in this microcontroller?
  The ADC module can be used by configuring the ADC control registers, selecting the ADC clock source, and enabling the ADC interrupts. The ADC module can operate in various modes, including single-shot mode, continuous conversion mode, and scan mode.
• What is the purpose of the COP (Computer Operating Properly) module?
  The COP module is a watchdog timer that monitors the microcontroller's operation and resets the device if it fails to respond within a specified time period. This helps to prevent the microcontroller from getting stuck in an infinite loop or malfunctioning due to software errors.
