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 indica-
ted in the GUI. Trigger pattern: preamble (32 bits "1") + 2 bits
"ST" (Start of Frame Code) + 2 bits "OP" (Frame Type Code, or
"OpCode") + 5 bits "PHYAD/PRTAD" (Physical Layer Entity
Address / Port Address) + 5 bits "REGAD/DEVAD" (Register
Address / Device Address) + 2 bits "TA" (turnaround time, X bits)
+ 16 bits "DATA/ADDRESS"
*RST: STARt
TRIGger<m>:MDIO:ST
<StartCode>
Selects the start of frame code of the frame pattern; available only in trigger type
"Data".
Note that Clause 22 is coded by "01", while Clause 45 is coded by "00", thus the lower
Clause number is represented by the higher parameter value.
Parameters:
<StartCode> ST00 | ST01 | ST0X
ST00
Clause 45
ST01
Clause 22
ST0X
Any permissible start pattern
*RST: ST0X
TRIGger<m>:MDIO:FRAMetype <FrameType>
Selects the Type of Frame code (or OP code, OpCode, operation code); available only
in trigger type "Data".
Note that the same OpCode may have different meanings in Clause 22 and Clause 45.
Parameters:
<FrameType> OP00 | OP01 | OP10 | OP11 | OPXX
OP00
Address frame (in Clause 45, only)
OP01
Write frame (in Clause 22 or Clause 45)
OP10
Read frame (in Clause 22) or Post-Read increment address
frame (in Clause 45)
OP11
Read frame (in Clause 45)
