Description
This field stores the 7-bit I²C address of remote
slave 7, attached to the remote Serializer. If an
I²C transaction (originating from the
Deserializer side) is addressed to Slave Alias7,
the transaction will be remapped to this
RW
0x00
address before it is passed across the
Bidirectional Control Channel to the remote
Serializer, where it is then passed to remote
slave 7.
A value of 0 in this field disables I²C access to
remote slave 7. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
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
RW
remapped to the I²C address specified in the
0x00
Slave ID0 register.
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 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
RW
remapped to the I²C address specified in the
0x00
Slave ID1 register.
A value of 0 in this field disables I²C access to
remote slave 1. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
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
RW
remapped to the I²C address specified in the
0x00
Slave ID2 register.
A value of 0 in this field disables I²C access to
remote slave 2. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
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
RW
remapped to the I²C address specified in the
0x00
Slave ID3 register.
A value of 0 in this field disables I²C access to
remote slave 3. Refer to I²C Pass-Through and
Multiple Device Addressing.
Reserved.
This field stores a 7-bit I²C address. Once set,

stored in this field. The transaction will then be
RW
remapped to the I²C address specified in the
0x00
Slave ID4 register.
A value of 0 in this field disables I²C access to
remote slave 4. Refer to I²C Pass-Through and
Multiple Device Addressing.
