This enables I2C buses to be multiplexed, so that you can select
|
|
one of several buses using some sort of control mechanism. The
|
|
bus select is handled automatically when that bus is accessed,
|
|
using a suitable I2C MUX driver.

If you say yes to this option, support will be included for an
|

I2C multimaster arbitration scheme using GPIOs and a challenge &

a GPIO.
