I2C GPIO PINS

Hi

My understanding is that possible to use the i2c interface on any GPIO pin. Is this statement correct?

No, the I2C peripherals are only available on certain pins.

You can emulate I2C using any GPIO pin using an open-drain output, but that's typically not desireable since it ties up the CPU.
