1)The I2C Monitor does only recognize regular I2C transfers, no I2C error conditions etc., thus it is not well suited for finding problems on I2C communication level. The monitor stretches SCL, i.e. the SCL line is held low occasionally. That may lead to problems with master or slave devices that do not support SCL stretching (like some I2C single master implementations). Tracii XL 2.0 offers a more sophisticated I2C Monitor, which includes time stamps for every byte and error recognition.
2)In conjunction with our level shifter product Levii buses are supported down to 1.8 volts. Our second level shifter product Optii works down to 1.5 volts and separates the I2C buses galvanically.
3)I2C slave and master cannot be used simultaneously.
