AM1806: I2C SCL was low after toggle SCL to resolve I2C hang

Part Number:AM1806

Dear Champs,

My customer faced I2C line hang and resolve it referring below. As other methods were not help to resolve their hang issue, they used recommendation 1 in below.

But, they found AM1806 I2C block was hang after several trials and SCL was low at this time.

AM1806 I2C block was not recovered even after power on/off.

Can you guess why SCL of AM1806 I2C was low and was not recovered?

Thanks and Best Regards,

SI.
