grey = payload data bytes
Table 13-23: Content of the "Decode results" table in the previous figures
Column Description
State Overall state of the packet: either OK or the relevant error condition (CRC, glitch-
ing, ...)
Start Start time of the packet.
PID PID type (OUT, IN, DATA0, ...)

Zooming on decoded results
The zoom functions allow you to analyze the decode results in more detail. If "Zoom
coupling" is enabled, the decode zoom and result table are synchronized; if you select
a row in the result table, this result is shown in the decode zoom.
