Reading values from registers

To enable reading of registers when in a debug session use one of the options:

Import a saved set of registers. For detailed information on exporting and importing registers refer to Exporting register values and Importing register values topics.
Manually crate a set of registers to interact with:
1. Open the Peripheral Registers view or the Arm System Registers view.
2. Select registers to be watched. A category, a group of registers, a peripheral, a cluster (if set), a register, a field (sequential bits within a register) can be selected. A minimal unit to be watched is a register - if you select a field the whole register will be added.
3. Press Enter or right-click the selection and click Watch Register(s) on the context menu or double-click the item.
4. The registers selected for reading appear in the Watch registers view.

The data are read from the registers of the RO (read-only) and RW (read-write) types at each debug action like a step, a resume, a stop, or a breakpoint. When the Hex and Binary cells are updated with the actual values of the registers, these values are displayed in yellow background.

Note: The Read on demand registers provide no values by default and display the “?” character on the initial appearance. To read a Read on demand register, select a register(s), right-click and select Read on the context menu.

To remove selected registers from the Watch registers view press Delete or right-click the selection and click Remove Register(s) on the context menu.
