MKL14Z64VLK4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 48 MHz, but it's recommended to use a clock frequency of 4 MHz or less to ensure reliable operation.
• How do I configure the pin muxing to use the desired peripherals?
  The pin muxing can be configured using the SIM_SCGC5 and PORTx_PCRn registers. Refer to the device's reference manual and the pin muxing chapter for more information.
• What is the minimum voltage required for the device to operate?
  The minimum voltage required for the device to operate is 1.71V, but it's recommended to use a voltage of 1.8V or higher for reliable operation.
• How do I use the low-power modes to reduce power consumption?
  The device has several low-power modes, including Stop, VLPR, and VLPW. These modes can be entered using the SMC_PMCTRL register. Refer to the device's reference manual for more information on how to use these modes.
• What is the maximum amount of current that can be sourced or sunk by a GPIO pin?
  The maximum amount of current that can be sourced or sunk by a GPIO pin is 4 mA, but it's recommended to limit the current to 2 mA or less to ensure reliable operation.
