CLK or SCK. Typo?

[Pandagineer]

Quick question:

• This link (see table header) uses "CLK" as one of the three SPI channels
• This link (see the image) uses "SCK" as one of the three SPI channels

Is this a typo, or am I misunderstanding? If the answer is "CLK", does this stand for "clock"? Thanks!

Yes, they are both the SPI clock.
The SPI clock is usually called CLK or SCK for Serial Clock

I will update the terminology on the web to use SCK in the table as well. Thanks for pointing it out!

Thank you. Serial clock: good to know
