data

Reconfiguration data for the PMA analog

settings. Refer to

Table 16-10

for valid

data values.

Refer to the Arria V Device Datasheet, the Cyclone V Device Datasheet, or the Stratix V Device Datasheet

for more information about the electrical characteristics of each device. The final values are currently

pending full characterization of the silicon.
