And I get a strange waveform with the test scenario:\r\n1. Host (FT2232H) sends a read cmd to slave, `I2cController.read(2)`\r\n2. In case slave has \"none\" data to send except for the ack\r\n\r\nThen I will see the waveform as below.\r\nMy question is, what will pyftdi deal with SDA for such condition?\r\n\r\n![2018-2-26 07-04-56](https://user-images.githubusercontent.com/32443068/36668492-78341940-1b2c-11e8-952b-660b8c6ca077.jpg)\r\n\r\n"}}
