MSP430F5244IRGZT Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MSP430F5244IRGZT?
  The maximum clock frequency of the MSP430F5244IRGZT is 25 MHz.
• How do I configure the MSP430F5244IRGZT to use an external crystal oscillator?
  To configure the MSP430F5244IRGZT to use an external crystal oscillator, connect the crystal to the XIN and XOUT pins, and set the FLLUNLOCK bit in the UCSCTL6 register to 1. Then, set the SELOSC bit in the UCSCTL4 register to 1 to select the external crystal oscillator as the clock source.
• What is the maximum current consumption of the MSP430F5244IRGZT?
  The maximum current consumption of the MSP430F5244IRGZT is approximately 2.1 mA at 25 MHz and 3.3V supply voltage.
• How do I use the built-in UART module on the MSP430F5244IRGZT?
  To use the built-in UART module on the MSP430F5244IRGZT, configure the UART module by setting the UART control registers (UCTL0, UCTL1, etc.) and enable the UART module by setting the UART enable bit (UE) in the UCTL0 register. Then, use the UART transmit and receive registers (UTXD, UTXBUF, URXD, etc.) to send and receive data.
• What is the purpose of the JTAG interface on the MSP430F5244IRGZT?
  The JTAG (Joint Test Action Group) interface on the MSP430F5244IRGZT is used for debugging and programming the device. It allows developers to debug and program the device using a JTAG interface adapter and software development tools such as Code Composer Studio.
