Here's an issue from the customer may need your help:

Project generated by CapTIvateDesignCenter. The goal is accomplish LIN communication by using UART(Auto baud rate mode).

This customer need to complete initializing and working normally in 100ms after power on. But he founded that the initializing of clock is too long. Here is his code(reference by demo).

And he test the initializing time is 80ms by toggle the IO. It's too long.

He need some help to optimize clock initializing time and quick startup.
