MSP430FE4232IPMR 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 8 MHz. However, it's recommended to use a clock frequency of 4 MHz or less to ensure reliable operation.
• How do I configure the device to use an external crystal oscillator?
  To configure the device to use an external crystal oscillator, you need to connect the crystal to the XIN and XOUT pins, and then configure the UCSCTL6 register to select the external crystal oscillator as the clock source.
• What is the minimum voltage required for the device to operate?
  The minimum voltage required for the device to operate is 1.8 V. However, it's recommended to operate the device at a voltage of 2.2 V or higher to ensure reliable operation.
• How do I use the built-in temperature sensor?
  The built-in temperature sensor can be enabled by setting the TEMPE bit in the SYSCTLTG register. The temperature sensor output can be read from the TEMPERATURE register. The output is a 12-bit value that represents the temperature in degrees Celsius.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 4 mA. However, it's recommended to limit the current to 2 mA or less to ensure reliable operation.
