010 - 111 : Reserved
Note that changing this setting will result in
some errors on the back channel for a short
period of time. If set over the control channel,
the Deserializer should first be programmed to
Auto-Ack operation to avoid a control channel
timeout due to lack of response from the
Serializer.

Remote Serializer ID
This field is normally loaded automatically from
the remote Serializer.
Freeze Serializer Device ID
Prevent auto-loading of the Serializer Device
ID from the Forward Channel. The ID is frozen
at the value written.
7-bit Remote Serializer Alias ID
Configures the decoder for detecting
transactions designated for an I2C Slave
device attached to the remote Deserializer.
The transaction is remapped to the address
specified in the Slave ID register. A value of 0
in this field disables access to the remote I2C
Slave.
Automatically Acknowledge all I2C writes to
the remote Serializer independent of the
forward channel lock state or status of the
remote Serializer Acknowledge
1: Enable
0: Disable
7-bit Remote Slave Device ID 0
Configures the physical I2C address of the
remote I2C Slave device attached to the
remote Serializer. If an I2C transaction is
addressed to the Slave Alias ID0, the
transaction is remapped to this address before
passing the transaction across the Bi-
directional Control Channel to the Serializer.
Reserved.
7-bit Remote Slave Device ID 1
Configures the physical I2C address of the
remote I2C Slave device attached to the
remote Serializer. If an I2C transaction is
addressed to the Slave Alias ID1, the
transaction is remapped to this address before
passing the transaction across the Bi-
directional Control Channel to the Serializer.
