Figure 13-18 I2C Block
DiagramThe I2C module consists of the following primary blocks:
Data is communicated to devices interfacing the I2C via the serial data pin (SDA) and the serial clock pin (SCL). These two wires carry information between the TI device and others connected to the I2C bus. Both SDA and SCL are bi-directional pins. They must be connected to a positive supply voltage via a pull-up resistor. When the bus is free, both pins are high. The driver of these two pins has an open-drain to perform the required wired-AND function.
