OMAP-L138

The data sheet seems to be unclear on this point. Can anyone confirm?

For background, I submitted the following documentation feedback:

    Adam,

      Thanks for the suggestion.  Would an update to section 5.34.3 be sufficient to clarify the confusion:

    5.34.3 Initial Scan Chain Configuration

    The first level of debug interface that sees the scan controller is the TAP router module. The debugger can configure the TAP router for serially linking up to 16 TAP controllers or individually scanning one of the TAP controllers without disrupting the IR state of the other TAPs.  The TAP router also allows access to the Boundary Scan Architecture (please refer to BSDL (SPRM377b or SPRM376b) for more information.

     

    Best Regards,

    Erik

    Hello Erik.

    Yes, I think that helps a lot!

    Only one minor suggested amendment is to match the open paren at please with a close paren at SPRM376b.

    Thanks!
