DWORD Matcher

DWORD Matcher is a DWORD pattern matcher that presents match and mask fields and a
K‐Code Mask field. K‐Codes are control characters that are always used in the first byte of
a four‐byte primitive. Of the K‐Code masks listed in the menu, D‐D‐D‐D is used for data
bytes, and K‐D‐D‐D is used for all primitives.
When you create a DWORD match, keep the following in mind:

SAS Data Pattern

When you create a SAS data pattern, keep the following in mind:
For example, for an SMP Request:
Pattern: 0x40000000
Mask: 0xFF000000
Offset: 0
SOF Type: SOF

SATA Data Pattern

When you create a SATA data pattern, keep the following in mind:
For example, for Register H ‐> D FIS:
Pattern: 0x00000027
Mask: 0x000000FF
Offset: 0
334
 
The pattern can be inside or outside of frames (it does not matter if the pattern
is inside a frame or not).
Because the pattern can be inside or outside of frames, there is no offset.
You can make user‐defined primitives. (This is the reason this feature was cre‐
ated.)
You can use any K/D pattern.
The pattern must be defined inside a frame that starts with a SOF or SOAF.
The pattern must be data only (no K‐codes/primitives).
The pattern must be defined at a specific offset in the frame.
The pattern and mask must be specified in the same format as specified in the
SAS standard: 
0x12345678 (hex)
where "1" is the first digit on the cable and is the MSB as given in the SAS Stan‐
dard.
The pattern must be defined inside a frame that starts with a SATA_SOF.
The pattern must be data only (no K‐codes/primitives).
The pattern must be defined at a specific offset in the frame.
The pattern and mask must be specified in the same format as specified in the
SATA Standard.
