I have a external clock =10Mhz or 20Mhz, can I use the clock used as the clock source for the 11u67 CPU?
My application as below: USB, uart, SPI, I2C, and RTC.

If YES!!

How to connect the clock to 11u67 CPU? Connect to XTALIN and XTALOUT?
But the max. voltage of crystal input voltage = 1.95V.

Is there has example?

Thank you.
