Mode selection
The interface can operate in the four following modes:
●
●
By default, it operates in slave mode.
The interface automatically switches from slave to master after it generates a START
condition and from master to slave in case of arbitration loss or a STOP generation, allowing
then Multi-Master capability.
Communication flow
In Master mode, it initiates a data transfer and generates the clock signal. A serial data
transfer always begins with a start condition and ends with a stop condition. Both start and
stop conditions are generated in master mode by software.
In Slave mode, the interface is capable of recognizing its own address (7-bit), and the
General Call address. The General Call address detection may be enabled or disabled by
software.
Data and addresses are transferred as 8-bit bytes, MSB first. The first byte following the
start condition is the address byte; it is always transmitted in Master mode.
A 9th clock pulse follows the 8 clock cycles of a byte transfer, during which the receiver must
send an acknowledge bit to the transmitter. Refer to
Figure 46. I²C bus protocol
Acknowledge may be enabled and disabled by software.
The I²C interface address and/or general call address can be selected by software.
The speed of the I²C interface may be selected between Standard (up to 100 kHz) and Fast
I²C (up to 400 kHz).
SDA/SCL line control
Transmitter mode: the interface holds the clock line low before transmission to wait for the
microcontroller to write the byte in the Data register.
Receiver mode: the interface holds the clock line low after reception to wait for the
microcontroller to read the byte in the Data register.
The SCL frequency (F
the I²C bus mode.
When the I²C cell is enabled, the SDA and SCL ports must be configured as floating inputs.
In this case, the value of the external pull-up resistor used depends on the application.
