Can MSP430FR2633 be connected to an external 7.3728MHz crystal? [Copy link]

In order to generate an accurate 115200 baud rate. How to configure it? I see that the examples are all connected to low-frequency crystal oscillators, or 16M DCO frequency, the accuracy is not high and it cannot be divided evenly.

430 external 7.3728MHz crystal oscillator

Why, how to say

This frequency is not too low and can be divided by 115200 baud rate without decimal configuration. However, according to the datasheet, this model supports up to 16MHz, but the XT pin does not seem to support HF

Yes, you need to check whether the datasheet supports this frequency.
