ATAPI User-Defined Decoding

Assigning a Script to ATAPI Commands

Open a sample, then choose User defined decoding … from the Configuration pull-down menu to

display the following dialog. Select ATAPI & SCSI command(s) and assign a user-defined script to

the sample.

Writing a Script for ATAPI Commands Decoding

If you want the SCSI fields of a UDD ATAPI commands to have the same color as a SCSI

command fields, do the following.

A user-defined ATAPI command has two or more fields.

The first field must have the name Operation Code, with length 1 byte. The options of the

Operation Code field must be defined in the DefineOptions section of the script.

OperationCode =(

"Vendor 99", 0x99;

"Vendor 66", 0x66;

"Vendor 77", 0x77);

For example:

OperationCode = AddField(CURPOS,8,"Operation Code",

"Operation Code","Operation Code");

Otherwise, different fields can be defined, and the fields of UDD ATAPI commands would have the

same color as ATA-command fields.

If the length of the last field is not certain, define the last field with the length

LengthOf(INPUTDATA)- CURPOS – 8, as in following example:

VendorSpecific = AddField(CURPOS, LengthOf(INPUTDATA)- CURPOS – 8 ,

"Vendor Specific","Vendor Specific","Vendor Specific");

1 2 ... 20 21 22 23 24 25 26 27 28
