Hi,
The manual mentions that the Clock and Data lines for I2C devices can be made either open-collector or bipolar. Open-collector requires a 4.7K pull-up resistor on the Clock and Data lines, and bipolar requires DEFINE I2C_SCLOUT 1.
What is the difference between each option?
Is there a performance difference?
Can you mix open-collector and bipolar on the same mcu?
