Dear forum,

We have a problem with I2C communication,
we are using I2C between FPGA(Master) and MCU(Slave).
Sometimes the SDA line(with 4.3Kohm conneted to 3.3v) is pulled low due to current flow in MCU(Slave) and this triggers a false start condition, but according to the I2C spec,. the start condition is always generated by a master,please let me know if there is any solution or guidance.

Regards
Paddu
