LPC54608 CLKOUT 25MHz

実奥山 — Wed, 03 Oct 2018 08:54:16 GMT

I use OM13092 board.

Can I take out 25MHz from CLKOUT?

The following clock can be chosen in CLKOUTSEL regster.

main_clk, clk_in,fro_hf,pll_clk etc.

Which clock should I choose?

Can FRO be set as 96MHz or 48MHz?

Is it main_clk to be equivalent to FRO?

I think I have to choose a clock bigger than 25MHz by CLKOUTSEL.

Please tell me how to make 25MHz.

Hi 実奥山,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd highly recommend you to use the MCUXpresso Config Tool to configure the clock, as the tool provides a graphical interaction interface to help the developer to do it.
