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
Deserializer.
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 and then to remote slave. 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.
