Peripheral Registers view

The Peripheral Registers view provides the structured view of the peripheral registers on the target hardware. If Arm® core registers are defined for the target device they are also present in this view.

The Peripheral Registers view is included in the Debug perspective by default. If the view was closed, reopen it from the menu by selecting Window > Show View > Other > Debug > Peripheral Registers.

The Peripheral Registers view presents the information about the peripheral registers in a tabular format. The Peripherals column displays the registers arranged in a hierarchy with the following levels (from top to bottom): a group of registers, a peripheral, a cluster (if set), a register, a field (sequential bits within a register). Any node in the hierarchy can be expanded or collapsed with a click.

The Description column provides the information about the object shown in the Peripherals column.

The remaining columns are populated for the “register” nodes:

Reset: Displays the reset value of the register in the hexadecimal format, for instance, 0x00000000. A mouse cursor moved over the hex value displays a tooltip with the binary equivalent.
Note: A “zero” value is displayed if the reset value is either set to 0x00000000 or not defined for the register.
Access: Displays the register access type (Read-Only, Read-Write, Write-Only).
Address: Displays the register address in memory.

The toolbar of the Peripheral Registers view includes the following buttons (from left to right):

	(Show structure)	Toggle for the Peripheral Registers view to show peripheral registers combined in categories.
	(View Menu)	Click to open the menu customizing the layout of the Peripheral Registers view. Options: Restore table layout: Sets the layout to its default.
	(Minimize)	Click to minimize the Peripheral Registers view.
	(Maximize)	Click to maximize the Peripheral Registers view. All other views are minimized and their icons appear at the right border of the main application window, each next to the dedicated Restore icon.
	(Restore)	Click to restore the Peripheral Registers view from minimal or maximal state.

The Peripheral Registers view context menu has the following options:

Find: Click to open the Find Element dialog. Search is available by register name, description or address.
Copy: Click to copy the selected registers text info to a system clipboard.
Watch Register(s): Click to send the selected registers to appear in the Watch registers view.
