MSP430F5418AIPNR datasheet by Texas Instruments

MSP430F5418AIPNR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MSP430F5418AIPNR?
  The maximum clock frequency of the MSP430F5418AIPNR is 25 MHz.
• How do I configure the MSP430F5418AIPNR to use an external crystal oscillator?
  To configure the MSP430F5418AIPNR to use an external crystal oscillator, connect the crystal to the XIN and XOUT pins, and set the XT2OFF bit in the SYSCTL2 register to 0. Then, set the SELOSC bit in the SYSCTL3 register to 1 to select the external oscillator as the clock source.
• What is the purpose of the JTAG pins on the MSP430F5418AIPNR?
  The JTAG pins (TCK, TMS, TDI, and TDO) on the MSP430F5418AIPNR are used for debugging and programming the device using a JTAG interface.
• How do I use the built-in UART on the MSP430F5418AIPNR?
  To use the built-in UART on the MSP430F5418AIPNR, configure the UART module by setting the UART control registers (UCTL0, UCTL1, etc.) and enable the UART clock using the UCSCTL6 register. Then, use the UART transmit and receive functions to send and receive data.
• What is the power consumption of the MSP430F5418AIPNR in low-power mode?
  The power consumption of the MSP430F5418AIPNR in low-power mode (LPM3) is approximately 0.5 μA/MHz, depending on the clock frequency and other factors.
