10.7 Read/write on the fly
The Read/Write on the Fly option permits you to non-intrusively read or write a value in the
RAM memory of the emulation chip while the application is executing.
When this option is selected in either the Memory window or the Watch window (indicated
by a checkmark beside the option in the contextual menu), all of the memory entries shown
in the window are continuously refreshed at one-second intervals while the program is
running. In these windows, the background turns yellow if the Read/Write on the Fly option
is active.
Figure 256. Memory and Watch windows with read/write on the fly
Note that when you scroll in the Memory Window, the newly visible memory entries turn
bold, to show that they are being updated, then change back to normal, indicating that they
are current and valid.
When the Read/Write on the Fly option is active, the only time that the values shown in the
Memory window may not be valid is during the direct editing of a memory value during the
running of a program. In this event, the edited value appears in red, indicating that it has not
yet been taken into account by the program, it then turns to bold black, to indicate that the
program is adjusting accordingly, and then finally, all entries are in normal weight black,
indicating that the window is valid and updated.
