Acknowledge may be enabled and disabled via
software.
The I2C interface address and/or general call
address can be selected via software.
The speed of the I2C interface may be selected
between Standard (0-100KHz) and Fast I2C (100-
400KHz).
14.3.3 SDA/SCL Line Control.
Transmitter mode: the interface holds the clock line
low before transmission, in order 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.
SCL frequency is controlled by a programmable
clock divider which depends on the I2C bus mode.
When the I2C cell is enabled, the SDA and SCL
pins must be configured as floating open-drain I/O.
The value of the external pull-up resistance used
depends on the application.
14.4 Functional Description
By default the I2C interface operates in Slave
mode (M/SL bit is cleared) except when it initiates
a transmit or receive sequence.
First, the interface frequency must be configured
using
the
related
bits
of
the
Configuration
Registers.
14.4.1 Slave Mode.
As soon as a start condition is detected, the
address is received from the SDA line and sent to
the shift register; then it is compared with the
address of the interface or the General Call
address (if selected by software).
