Possible to query Core Clock speed? K10

Is there a method to query the System core speed?


I’ve got a 12MHz external clock that I’m converting to 100MHz via the PLL and would like to know EXACTLY how close to 100MHZ it’s actually running. I need that number to ensure my UART, SPI, etc are accurate. 


Now I can measure the Trace Clockout signal, but that'll be for a single MCU and I want to know this value for every unit we build.
