Error
. When asserted, indicates an error.
This bit is asserted if any of the following
conditions occur:
• The channel address is invalid.
• The PHY address is invalid.
• The PMA offset is invalid.

R
Busy
. When asserted, indicates that a
reconfiguration operation is in progress.

W
Read
. Writing a 1 to this bit triggers a read
operation.
[0]
W

pma offset
Specifies the offset of the PMA analog
describes the valid offset values.
7’h0C

data
Reconfiguration data for the PMA analog
settings. Refer to
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.
