IC SINGLE MASTER BUS INTERFACE (Cont’d)
Acknowledge may be enabled and disabled by
software.
The speed of the I2C interface may be selected
between Standard (0-100KHz) and Fast I2C (100-
400KHz).
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 (Fscl) is controlled by a
programmable clock divider which depends on the
I2C bus mode.
When the I2C cell is enabled, the SDA and SCL
ports must be configured as floating open-drain
output or floating input. 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.
