Physical Layer Events
Physical layer events are events related to reliable packet transfers such as transmission errors and protocol errors. Most
physical layer events trigger the standard RapidIO error recovery function, which ensures packet delivery. A low rate of
transmission errors will occur on a RapidIO link.
RapidIO physical layer events are in
. This table has four columns:
• Event Name – The short form by which the event is consistently identified.
• Detection Enable – Any register settings required to enable detection of the event. “Always Detected” means that there are
no controls to disable detection of the event.
• Information Capture Enable – The register settings required to enable the event to supply the leaky bucket. These register
settings also enable capture of information associated with the event.
• Information Captured – Summary of information captured for the event, as well as status bit which indicates the event was
detected. Multiple status bits may be set, however information is only captured for the first enabled event. Subsequent
events do not have any information captured. The values in the “Information Captured” column are described in

Description
No Info
No information is captured for this event.
Control Symbol
Control symbol information is captured for the event. This information is in the following registers:
Port {0..17} Attributes Capture CSR
Port {0..17} Capture 0 CSR
Port {0..17} Capture 1 CSR
.
Note that information is located only in the
if IDLE2/long control symbols are
active.
