"However, there are also some limitations when using FlexIO to emulate I2C bus master. For example, the I2C features such as multi-master/arbitration, handshaking, and clock stretching are not supported. Also, it is difficult to emulate I2C bus slave using FlexIO."
It states it is difficult to emulate I2C slave, the question is whether is possible. Also whether this limitation applies as well to K3 FlexIO.
If it is possible to emulate I2C, is there any available information about what are the challenges to overcome
