7-bit Remote Slave Device Alias ID 0 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 0 register. A value of 0 in this field
disables access to the remote I2C Slave.
Reserved
Number of Back Channel CRC errors – 8 least significant bits.
Cleared by 0x04[5]
Number of Back Channel CRC errors – 8 most significant bits.
Cleared by 0x04[5]
Reserved
Back Channel CRC error during BIST communication with
Deserializer. This bit is cleared upon loss of link, restart of BIST, or
assertion of CRC ERROR RESET in register 0x04.
0: No CRC errors detected during BIST (default)
1: CRC Errors detected during BIST
