ST72651AR6
I²C SINGLE MASTER BUS INTERFACE (Cont’d)
Acknowledge may be enabled and disabled by
software.
The speed of the I
between Standard (up to 100KHz) and Fast I
(up to 400KHz).
SDA/SCL Line Control
Transmitter mode: the interface holds the clock
line low before transmission to wait for the micro-
controller 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.

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 resistance
used depends on the application.
When the I2C cell is disabled, the SDA and SCL
ports revert to being standard I/O port pins.
