Alias ID 0
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.

BIST CRC
Error
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.

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.

0: Disable GPIO control from remote Deserializer
(default)
1: Enable GPIO control from remote Deserializer.
The GPIO pin will be an output, and the value is
received from the remote Deserializer.
