USB2/USB2-HSIC Decode and Trigger
4. In Compare Type, choose to compare Data Values or Data Lengths to find a match.
5. If you chose to compare lengths, enter the Cmp. Opr. (operator) and Length (in bytes) that define the
trigger criteria (e.g., Trigger if Data0 length is greater than 4 bytes).
If you chose to compare values, enter the Cmp. Opr. (operator), At position, and a reference Data (1-16
Bytes) pattern that define the trigger criteria (e.g., Trigger if the value at position x in Data0 is equal to y).
TRIGGER ON HANDSHAKE PATTERN
1. Choose Pattern Type Packet and Category Handshake.
2. Select the handshake type that will fire the trigger: Any Type, ACK, NAK, STALL, NYET (High Speed only),
or Error) (High Speed only).
TRIGGER ON USER-DEFINED PATTERN
1. Choose Pattern Type Packet and Category User Define.
2. Choose to enter values in Binary or Hexadecimal (Hex) format. The selection propagates throughout the
entire trigger setup. Toggling between formats does not result in loss of information, but will transform
the appearance of values.
