Description
7-bit Deserializer Device ID Configures the I²C Slave ID
of the remote Deserializer. A value of 0 in this field
disables I²C access to the remote Deserializer. This field
is automatically configured by the Bidirectional Control
Channel once RX Lock has been detected. Software may
overwrite this value, but should also assert the FREEZE
DEVICE ID bit to prevent overwriting by the Bidirectional
Control Channel.
1: Prevents auto-loading of the Deserializer Device ID by
the bidirectional control channel. The ID will be frozen at
the value written.
0: Update
7-bit Remote Deserializer Device Alias ID Configures the
decoder for detecting transactions designated for an I²C
Deserializer device. The transaction will be remapped to
the address specified in the DES ID register.
A value of 0 in this field disables access to the remote
I²C Slave.
Reserved
7-bit Remote Slave Device ID Configures the physical I²C
address of the remote I²C Slave device attached to the
remote Deserializer. If an I²C transaction is addressed to
the Slave Alias ID, the transaction will be remapped to
this address before passing the transaction across the
Bidirectional Control Channel to the Deserializer. A value
of 0 in this field disables access to the remote I²C slave.
Reserved
7-bit Remote Slave Device Alias ID 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 ID register. A value of 0 in this field disables
access to the remote I²C Slave.
