12. 2-Wire Serial-Port Operation

The 2-wire serial-port interface supports a bi-directional data transmission protocol with device addressing.

Connections to the bus are made through SCL and SDA. Timing diagrams for the 2-wire serial port can be found in

Figure 4. Within the bus specifications, a standard mode (100kHz clock rate) and a fast mode (400kHz clock rate) are

defined. The Module works in both modes.

The following bus protocol has been defined:Data transfer may be initiated only when the bus is not busy. During data transfer, the data line must remain stable

whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as control signals.

- Bus not busy: Both data and clock lines remain high.

- Start data transfer: A change in the state of the data line from high to low while the clock is high defines a START

condition.

- Stop data transfer: A change in the state of the data line from low to high while the clock line is high defines the STOP

condition.

- Data valid: The state of the data line represents valid data when, after a START condition, the data line is stable for

the duration of the high period of the clock signal. The data on the line can be changed during the low period of the clock

signal. There is one clock pulse per bit of data. Figure 4 detail how data transfer is accomplished on the 2-wire bus.

- Clock and Data Transitions: The SCL pin is normally pulled high with an external resistor or device. Data on the SCL

pin may only change during SDA -low time periods. Data changes during SDA -high periods will indicate a START or

STOP condition depending on the conditions discussed below.

- START Condition: A high-to-low transition of SCL with SDA high is a START condition that must precede any other

command. See the timing diagrams in Figure 4 for further details.

- STOP Condition: A low-to-high transition of SCL with SDA high is a STOP condition. After a read or write sequence,

the stop command places the condition into a low-power mode.

- Acknowledge: All address and data bytes are transmitted through a serial protocol. The Controller pulls the SCL line

low during the ninth clock pulse to acknowledge that it has received each word.
