Re: I2C using

The chip is advertised for having a HW i2c peripheral, but all the libs I saw simply bitbang it on GPIO pins, what's up with that mates?

Where did you see such claims? There's no externally available hardware i2c on this chip.
8.4.1 Master SI / SPI Control (Optional)
The master serial interface (SI) can operate in two, three or four-wire bus configurations to control the EEPROM or other I2C/SPI devices. Multiple I2C devices with different device addresses are supported by sharing the 2-wire bus.
