MC68HC000CEI16 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the MC68HC000CEI16?
  The maximum operating temperature range for the MC68HC000CEI16 is -40°C to 85°C.
• How do I configure the clock source for the MC68HC000CEI16?
  The clock source for the MC68HC000CEI16 can be configured using the Clock Generator Module (CGM) registers. The CGM allows the selection of the clock source, clock frequency, and clock mode.
• What is the maximum clock frequency supported by the MC68HC000CEI16?
  The maximum clock frequency supported by the MC68HC000CEI16 is 16 MHz.
• How do I implement a watchdog timer on the MC68HC000CEI16?
  The MC68HC000CEI16 has a built-in Computer Operating Properly (COP) watchdog timer that can be enabled and configured using the COP register. The COP timer can be used to reset the microcontroller if it fails to respond within a specified time period.
• What is the purpose of the VPP pin on the MC68HC000CEI16?
  The VPP (Voltage Programming Pin) is used to program the flash memory on the MC68HC000CEI16. It is not used during normal operation and should be tied to VCC or left unconnected.
