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
(both Standard and Fast I
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.
When the I
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.
