MSP430F6779AIPZ 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 use an external crystal oscillator, connect the crystal to the XIN and XOUT pins, and configure the FLL (Frequency Locked Loop) to use the external crystal. This is done by setting the XT2OFF bit in the UCSCTL6 register to 0, and configuring the FLL multiplier and divider values in the UCSCTL0 and UCSCTL1 registers.
• 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 and to prevent overheating.
• How do I use the built-in temperature sensor?
  The built-in temperature sensor is a 10-bit analog-to-digital converter (ADC) that measures the temperature of the device. To use the temperature sensor, configure the ADC to use the internal temperature sensor as the input channel, and read the temperature value from the ADC result registers.
• What is the purpose of the JTAG pins, and how do I use them?
  The JTAG pins (TCK, TMS, TDI, and TDO) are used for debugging and programming the device. They can be used with a JTAG debugger or programmer to load code, debug, and test the device.
