"Data"
Sets the trigger to the data field. For more information on the data
condition, see MDIO in the Ethernet standard. The trigger instant is at
the end of the frame after the last data bit, as indicated in the GUI.
Note: All data triggers are always at the end of the frame, even if the
specified pattern to trigger for is at a different position within the data
word.
Trigger pattern: preamble (32 bits "1") + "ST" (2 bits, Start of Frame
Code) + "OP" (2 bits, operation code or frame type code) + "PHYAD/
PRTAD" (5 bits, Physical Layer Entity Address / Port Address) +
"REGAD/DEVAD" (5 bits, Register Address / Device Address) + "TA"
(2 "X" bits, turnaround time) + "DATA/ADDRESS" (16 bits)
For the parameters to be specified, see "ST" on page 808, "OP"
on page 808, "PHYAD/PRTAD" on page 809, "REGAD/DEVAD"
on page 809, and "DATA/ADDRESS" on page 809.
