SPI maximum clock frequency in i.MXRT1170

[neetha_jyothish]

Hi

I am trying to find the maximum SCK frequency that is supported by i.MX RT 1170. The datasheet mentions that the max. frequency is fperiph/2 as shown in the figure: 

I tried to find fperiph in the reference manual, but I couldn't find it. But I did come across something called LPSPI1_CLK_ROOT. Could someone please explain whether fperiph is the same as LSPI1_CLK_ROOT?

Thanks @DanielRuvalcaba , that cleared my doubt.

Hi,

fperiph is LPSPI peripheral clock. I'd recommend you to take a look to the CCM in the Reference Manual.

You can also take a look to this article.

Regards,

Daniel.
