PRODUCTION DATA
Depending on the device variant (see Section 6), the device can support a low-frequency crystal (32 kHz) on the LFXT pins, a high-frequency crystal on the HFXT pins, or both. External bypass capacitors for the crystal oscillator pins are required.
It is also possible to apply digital clock signals to the LFXIN and HFXIN input pins that meet the specifications of the respective oscillator if the appropriate LFXTBYPASS or HFXTBYPASS mode is selected. In this case, the associated LFXOUT and HFXOUT pins can be used for other purposes. If they are left unused, they must be terminated according to Section 7.6.
Figure 10-3 shows a typical connection diagram.
See MSP430 32-kHz Crystal Oscillators for more information on selecting, testing, and designing a crystal oscillator with the MSP MCUs.
