What is the I2C protocol stack in UEFI?
I2C Protocol Stack The platform hardware designer chooses the bus layout based upon the platform, I2C chip and software requirements. The design uses switches to truncate the bus to enable higher bus frequencies for a subset of devices which are placed closer to the controller. When the switch is on, the extended bus must operate at a lower bus frequency. The design uses multiplexer to create separate address spaces enabling the use of multiple devices which would otherwise have conflicting addresses.
