Each host controller has an independent reset associated with it. Control of these resets is accessed through the Reset Register.

Each host controller and DMA will be in reset state once powered ON and require SW (BIOS or driver) to write into specific reset register to bring the controller from reset state into operational mode.

Note:To avoid a potential I2C peripheral deadlock condition where the reset goes active in the middle of a transaction, the I2C controller must be idle before a reset can be initiated.
