issleeping

Display whether the specified processor is sleeping.

Syntax

[result =] [[px]] issleeping

Where:

[px]	is the viewpoint override, including punctuation ( [ ] ), specifying that the viewpoint is temporarily set to processor x of the boundary scan chain.  The processor can be specified as px (where x is the processor ID), or an alias you have defined for a given processor ID.  ALL cannot be used as a viewpoint override.
result	specifies a debug variable to which the function return value is assigned. If result is not specified, the return value is displayed on the next line of the screen.

Discussion
