MC68HC000CEI16R datasheet by Freescale Semiconductor

MC68HC000CEI16R Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The MC68HC000CEI16R can operate from -40°C to 125°C, making it suitable for industrial and automotive applications.
• How do I configure the clock source for this microcontroller?
  The MC68HC000CEI16R can use an external clock source or an internal clock source. To configure the clock source, you need to set the CLKSEL bits in the Option Register (OPT) to select the desired clock source.
• What is the maximum frequency for the external clock source?
  The maximum frequency for the external clock source is 20 MHz.
• How do I reset the microcontroller?
  The MC68HC000CEI16R can be reset by asserting the RESET pin low for at least 10 clock cycles. You can also use the software reset instruction (SWI) to reset the microcontroller.
• What is the purpose of the VPP pin?
  The VPP (Programming Voltage) pin is used to supply the programming voltage during flash programming. It should be connected to VCC during normal operation.
