Explore the i2c-bus.org website to understand the different speed modes of the I2C bus and how the I2C hardware fundamentally works. Specifically, identify the maximum transfer rates for 'Fast Mode', 'Fast Mode Plus', and 'High Speed Mode'. Additionally, describe the basic hardware mechanism by which data is transferred on the I2C bus, as explained in the 'How I2C Hardware Works' section.
Navigate to 'https://www.i2c-bus.org/'. Click on the 'Fast Mode' link (ID 75) in the sidebar. Identify the maximum transfer rate for Fast Mode. Click on the 'Fast Mode Plus' link (ID 77) in the sidebar. Identify the maximum transfer rate for Fast Mode Plus. Click on the 'High Speed Mode' link (ID 79) in the sidebar. Identify the maximum transfer rate for High Speed Mode. Click on the 'I2C Primer' link (ID 17) in the sidebar. Click on the 'How I2C Hardware Works' link (ID 23) in the I2C Primer sidebar. Describe the basic hardware mechanism for data transfer on the I2C bus as explained on this page.
State the maximum transfer rate for Fast Mode as 400 kbit/s. State the maximum transfer rate for Fast Mode Plus as 1 Mbit/s. State the maximum transfer rate for High Speed Mode as 3.4 Mbit/s. Describe that I2C uses two lines, SDA (data) and SCL (clock), which are open-drain and require pull-up resistors to VCC. Explain that data is transferred bit by bit, synchronized by the clock line, and that devices pull the lines low to transmit a '0' and release them to transmit a '1'.
