Hi @ROSELJR
Please accept my apologies for the delay. We are overloaded on the requests. I really appreciate your patience.
Regarding your question, you could check the answer of one of our colaborators years ago on this post of our community: https://community.nxp.com/t5/Kinetis-Microcontrollers/SMBUS-I2C-on-same-bus/td-p/199370
Also, remember that if you need to use more than 100kHz on I2C bus, you won't be able to combine SMBUS because its maximum is 100kHz, so you will need to work below this frequency clock.
Hope the information was helpful, please let me know if you have more questions.
Thank you.
Sincerely,
Pablo Avalos.
