My customer is reporting a I2C latch issue about TUSB544. Said:
1. The SDA was hold low, sending more SCK, it is not recovered;
2. Power down our device, the SDA was released;
3. Add some capacitors on SDA can solve the issue.
I am asking them to capture the waveform, to see if there is some margin issue on the I2C timing. But can you tell if our device have the timeout of the I2C?
