Notice the folder icons; the lines they mark categorize the task information. You
can hide any information that is not of interest to you by clicking on any open
folder, or expose such hidden information by clicking on any closed folder.
Figure 6-5 shows another task browser running on the same target architecture,
but with most of the hardware registers hidden.

6.6.2 The Semaphore Browser
To inspect a semaphore, enter either its name or its semaphore ID in the main target
browser’s Show box. A specialized semaphore browser appears, similar to the one
shown in Figure 6-6. The semaphore browser displays both information about the
semaphore itself (under the heading Attributes), and the complete queue of tasks
blocked on that semaphore, under the heading Blocked Tasks. The title bar shows
the semaphore ID, to help you distinguish browser displays for multiple
semaphores.
Figure 6-6 shows a binary semaphore with one blocked task in its queue. As in
other browser windows, you can click on the folders to control detail. To start a
browser for any queued task, click on the task name or ID; both are displayed for
each task.
