Why do I create I2C with flexio ,after initialization the pin register is always 0

[jinyun1984]

The value of the PCC register is 0xc1000000, and the power on should also be successful. The value of the CTRL register is 1. Is there anything else that needs to be set?The chip is s32k144.

Hi,

Could you please elaborate on the description?

Have you configured SOSC clock source?
