Description
This field stores a 7-bit I²C address. Once set, it
configures the Serializer to accept any transaction
designated for the I²C address stored in this field. The
transaction will then be remapped to the I²C address
specified in the DES ID register.
A value of 0 in this field disables I²C access to the
remote Deserializer. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
This field stores the 7-bit I²C address of the remote slave
attached to the remote Deserializer. If an I²C transaction
(originating from the Serializer side) is addressed to
Slave Alias, the transaction will be remapped to this
address before it is passed across the Bidirectional
Control Channel to the remote Deserializer, where it is
then passed to the remote slave.
A value of 0 in this field disables I²C access to the
remote slave. Refer to I²C Pass-Through and Multiple
Device Addressing.
Reserved.
