bidirectional. Both are open-drain signals and require pull-up resistors. The host controller is a bus master
device and drives SCL at approximately 60 kHz during data transfers and places SCL in a
high-impedance state (0 frequency) during bus idle states. The serial EEPROM is a bus slave device and
must acknowledge a slave address equal to A0h. Figure 3-3 illustrates an example application
implementing the two-wire serial bus.
