MSP430F2131IDGVR 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 16 MHz, but it's recommended to use 12 MHz or lower for optimal performance and to ensure that the device operates within its specified parameters.
• How do I configure the MSP430F2131IDGVR for low-power operation?
  To configure the MSP430F2131IDGVR for low-power operation, you can use the Power Management Module (PMM) to select the lowest possible clock frequency, disable unused peripherals, and use the Low Power Mode (LPM) feature. You can also use the Dynamic Voltage Scaling (DVS) feature to reduce the voltage supply to the core and peripherals.
• 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 per pin, but it's recommended to limit the current to 2 mA per pin to ensure reliable operation and to prevent damage to the device.
• How do I use the Universal Serial Communication Interface (USCI) module for UART, SPI, or I2C communication?
  The USCI module can be configured for UART, SPI, or I2C communication by setting the appropriate control registers and using the corresponding protocol-specific registers. You can refer to the MSP430F2131IDGVR user's guide and the TI-provided example code for more information.
• What is the purpose of the JTAG pins, and how do I use them for debugging?
  The JTAG pins are used for debugging and programming the device using the Joint Test Action Group (JTAG) interface. You can use a JTAG debugger, such as the TI XDS100v2, to connect to the device and perform debugging operations, such as single-stepping, breakpoints, and register examination.
