0x7D Slave Alias[7]
7:1
RW
0x00 Slave Alias 7-bit Remote Slave Device Alias ID 7
ID 7
Configures the decoder for detecting transactions
designated for an I²C Slave device attached to the
remote Deserializer. The transaction will be remapped
to the address specified in the Slave ID7 register. A
value of 0 in this field disables access to the remote
I²C Slave.
