Q: Does the 66AK2H06 I2C support the clock stretching feature?
My customer is experiencing an Arbitration Lost error in I2C communication for a product using 66AK2H06 and is investigating the cause. Looking at the waveform at the time of the error, there is a point where the SCL suddenly goes from High to Low just before the data ACK, and we suspect that the slave side may have performed clock stretching.(66AK2H06 is the master side.)
There are many unclear points about the situation, but first of all, please let me know if the I2C of 66AK2H06 supports the clock stretching function.
