Figure 4.7. The I/O registers view
Register values that are changed since last update are highlighted with yellow. When expanding the register nodes
in the tree of the view, the left column is auto expanded to fit the content.
For bit registers consisting of only one bit, a flag, the value can be toggled by clicking the value, and then checking
or un-checking the check-box.
By default the most common registers are presented in the view. However all registers known to GRMON may
be presented by pressing the icon on the right top corner. Note that doing so may change the state of the hardware
since reading certain registers may affect the state of the hardware.
Values for registers are retrieved only when they are to be shown in the view. Unless another view or operation
requires the values of the registers to be loaded, the values are not retrieved until they are visible in the view.
The register values are updated from the target hardware because of a few different reason.
• Edit - when the value of a register changes as result of an edit
• Suspend - when a process is suspended, the visible registers are updated
• Refresh - the values can be re-fetched from the target hardware by pressing the refresh button, or by using
the periodic refresh.
NOTE:Note that changed values will not be highlighted if the register values are update via refresh, either by
clicking the refresh button or by periodic refreshes.
Click the arrow down icon in the toolbar to access the view pull down menu. Under the Layout item are different
options on how to customize the appearance of the view. For instance can which columns to display be specified
under Select Columns....
