MSP430F2274TRHAT datasheet by Texas Instruments

MSP430F2274TRHAT 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. However, it's recommended to use a clock frequency of 12 MHz or less to ensure reliable operation.
• How do I configure the MSP430F2274TRHAT for low-power operation?
  To configure the MSP430F2274TRHAT for low-power operation, you can use the Power Management Module (PMM) to control the power modes. You can also use the Low Power Mode (LPM) to reduce power consumption. Additionally, you can disable unused peripherals and use the Dynamic Voltage Scaling (DVS) feature to optimize power consumption.
• 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.
• How do I use the Universal Serial Communication Interface (USCI) module?
  The USCI module can be used for UART, SPI, or I2C communication. To use the USCI module, you need to configure the module using the UCAxCTL0 and UCAxCTL1 registers. You also need to configure the clock source and baud rate using the UCSxCTLW and UCSxBRW registers.
• What is the purpose of the JTAG interface?
  The JTAG (Joint Test Action Group) interface is used for debugging and programming the MSP430F2274TRHAT. It allows you to connect a debugger or programmer to the device and perform tasks such as flashing the firmware, debugging code, and monitoring system states.
