Other Parts Discussed in Thread: MSP430F149, MSP430F417, , MSP430F2619
I am trying to change the chipset of the system using the MSP430F149.
We are reviewing the MSP430 series, which is judged to be a reasonably similar chipset.
There is a strange problem during H / W configuration.
The original system uses an external clock of 3.6864MHz.
The MSP430F149 has a 3.3V output on the XOUT pin when powered on.
Therefore, the external crystal vibrates.
However, the MSP430F2491, MSP430F2619, and MSP430F417 output only about 500 mV when the power is turned on.
Crystal oscillation does not work ...
How can I get 3.3v output from the XIN and XOUT pins?
Do you need software configuration?
Do you need hardware configuration?
Is there a document to reference?
Is there any code to reference?
