Function Description
Slave
Device
Alias ID
7-bit Remote Slave Device Alias ID
Assigns an Alias ID to 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.

communication with Deserializer.
The bit is cleared upon loss of link, restart of BIST,
or assertion of CRC ERROR RESET in register
0x04.

DES Error
Back channel CRC error during communication
with Deserializer.
The bit is cleared upon loss of link or assertion of
CRC ERROR RESET in register 0x04.

GPIO0
Output
Value
Local GPIO output value
This value is output on the GPIO pin when the
GPIO function is enabled, the local GPIO direction
is Output, and remote GPIO control is disabled.
GPIO0
Remote
Enable
Remote GPIO control
1: Enable GPIO control from remote Deserializer.
The GPIO pin will be an output, and the value is
received from the remote Deserializer.
0: Disable GPIO control from remote Deserializer.
