Hi
Chip is MCXN947, from the spec, it says I3C two-wire multidrop bus that is capable of 12.5 MHz clock speeds with up to 11 devices.
In fact, I cannot get 12.5M clock, How can I config if we want run up to 12.5MHz baudrate?
Thanks.
Hi @Harry_Zhang
Thanks for your reply.
Have you check the clock, EXAMPLE_I3C_PP_BAUDRATE is 1.25MHz by default. If I set to 12.5MHz, the clock isn't correct.

Hi @yvan_yan
You can refer to the frdmmcxn947_i3c_polling_b2b_transfer_master examples in the SDK.

Could you help me check this problem?
We can get I3C 10MHz clock, but we cannot get higher
I will check it and reply to you.
Thanks a lot. Looking forward to your reply.
We can run I3C sdr mode in 12.5MHz.
But i3c hdr-ddr mode cannot run above 3MHz, Is i3c ddr mode capable of operating in 12.5MHz?
Yes,
According to the MCXNx4x data sheet.
Both SDR and DDR can run at 12.5M.
