Hi

Does the CY7C68013A provide a method for i2c stuck bus recovery?  i.e. if a device connected to the master is holding the SDA line low can the CY7C68013A clock out the slave device so that it releases SDA?

Hi,

No, the specific operation cannot be performed in FX2LP.

That's a pity.
Are there any recommendations how to handle such an issue?

Hello Marcus,

An option is to reset the slave.  A GPIO in Open-drain mode can be connected to the SCL line.

You can try to manually toggle the SCL line to force the slave to release SDA.

Dear Mallika,

I hoped that there would be another solution than sacrifice one of the other IO-Ports.
But thank you anyway,
Marcus
