8.5.2. I2C - Inter-integrated Circuit
The LE910Cx supports an I2C interface on the following pins:
 B11 - I2C_SCL
 B10 - I2C_SDA
The I2C can also be used externally by the end customer application.
In addition, SW emulated I2C functionality can be used on GPIO pins 1-10. Any GPIO
(among GPIO 1-10) can be configured as SCL or SDA.
LE910Cx only supports I2C Master Mode.
