ZHCSEA0F October 2015 – December 2019 MSP430FR2433
This device supports only a low-frequency crystal (32 kHz) on the XIN and XOUT pins. External bypass capacitors for the crystal oscillator pins are required.
It is also possible to apply digital clock signals to the XIN input pin that meet the specifications of the respective oscillator if the appropriate XT1BYPASS mode is selected. In this case, the associated XOUT pin can be used for other purposes. If the XIN and XOUT pins are not used, they must be terminated according to Section 4.6.
Figure 7-2 shows a typical connection diagram.
See MSP430 32-kHz Crystal Oscillators for more information on selecting, testing, and designing a crystal oscillator with the MSP430 devices.
