MCGFFCLK cannot be found in Clocking diagram the KL26 Reference Manual

Hi,

I read the MCG chapter in KL26 reference manual, found a MCGFFCLK clock, but I cannot find where it is in the Clocking diagram.

The sentence is "The MCG Fixed Frequency Clock (MCGFFCLK) provides a fixed frequency clock

source for other on-chip peripherals; see the block diagram."

But nothing is about the block diagram.

Thanks,

Henry Xin

Hi, Henry Xin

For Kl25, Pls refer to the section 5.3 High-Level device clocking diagram, especially Figure 5-1. Clocking diagram, I do not think the KL25 has defined the MCGFFCLK clock source, none of peripheral uses the MCGFFCLK clock.

Hi XiangJun,

Thanks. I cannot find the MCGFFCLK in the High-Level device clocking diagram in the datasheet.

Is it possible that "MCGFFCLK" is MCGFLLCK with a wrong print?
