This field stores the 7-bit I²C address of the
remote Serializer. If an I²C transaction
(originating from the Deserializer side) is
addressed to SER Alias, the transaction will be
remapped to this address before it is passed
across the Bidirectional Control Channel to the
remote Serializer.
This field is automatically configured by the
Bidirectional Control Channel once RX LOCK
has been detected. Software may overwrite this
value, but the Freeze Device ID bit should also
be asserted to prevent overwriting by the
Bidirectional Control Channel.
A value of 0 in this field disables I²C access to
the remote Serializer. Refer to I²C Pass-
Through and Multiple Device Addressing.
Freeze Serializer Device ID.
1: Prevents auto-loading of the Serializer
Device ID from the forward channel. The ID will
be frozen at the value written.
0: Allows auto-loading of the Serializer Device
ID from the forward channel.
This field stores a 7-bit I²C address. Once set,
it configures the Deserializer 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
SER ID register.
A value of 0 in this field disables I²C access to
the remote Serializer. Refer to I²C Pass-
Through and Multiple Device Addressing.
Reserved.
This field stores the 7-bit I²C address of remote
slave 0, attached to the remote Serializer. If an
I²C transaction (originating from the
Deserializer side) is addressed to Slave Alias0,
the transaction will be remapped to this
address before it is passed across the
Bidirectional Control Channel to the remote
Serializer, where it is then passed to remote
slave 0.
A value of 0 in this field disables I²C access to
remote slave 0. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
This field stores the 7-bit I²C address of remote
slave 1, attached to the remote Serializer. If an
I²C transaction (originating from the
Deserializer side) is addressed to Slave Alias1,
the transaction will be remapped to this
address before it is passed across the
Bidirectional Control Channel to the remote
Serializer, where it is then passed to remote
slave 1.
A value of 0 in this field disables I²C access to
remote slave 1. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
