    Hi,

    I have a problem with the I2C slave read (or transmit) operation.

    Sometimes, when the master does a Read operation in my device, it only reads FF's.

    It seems as if the clock streching wasn't working (it's set), so the master is just reading the SDA pull-up. It only happens sometimes, so maybe it's an interrupt related issue.

    Has someone experienced this before?

    Thank you
