Terms for Clock Control Module

Patrick Ruf

Hi,

Can anyone from TI please tell me what the meaning of the following terms are:

- L4FW
- OCPWP
- L3_INSTR
- EMIF_FW

I have found this terms in the Clock Control Register List (AM335x TRM) but there are no descriptions what they mean or what these modules do.
Any help is appreciated. Thanks.

Best regards,

Patrick

Hi Biser,

Thanks. What about the other two? "L3_INSTR" was also asked somewhere else in the E2E but no answer so far.
OCPWP could be "Open Core Protocol..." as from your link. What does the "WP" means?

Thanks.

OCPWP is the OCP Watchpoint, which is kind of like a packet sniffer for the L3 interconnect. No idea how to configure it, documentation seems to be lacking.

L3_INSTR shows up in interconnect diagrams of various processors, also labeled as "Instrumentation L3"... it appears to be a specialized interconnect used to carry trace data (such as from OCPWP) to the DebugSS.
