I2C interface
The integrated I
two-line SDA/SCL in accordance with the I
operate in slave mode, in master mode or in multi-master mode. It can receive and transmit
data using 7-bit or 10-bit addressing. Data can be transferred at speeds up to 400 Kbit/s

The module can generate three different types of interrupt:
●

These requests are issued to the interrupt controller by three different lines, and identified as
Error, Transmit, and Receive interrupt lines.

P4.7 (where SCL and SDA are respectively mapped as alternate functions) are
automatically configured as bidirectional open-drain: the value of the external pull-up
resistor depends on the application. P4, DP4 and ODP4 cannot influence the pin
configuration.
