Modify register dialog
Modify register dialog includes three representations of a register value:
•Hexadecimal in the edit field
•Decimal in the edit field
•Binary using all the check-boxes; where every check-box represents a bit in the register.
If a value of one field is changed then other fields are updated accordingly.
Modify register dialog allows you to change:
•General purpose registers
•Registers containing status flags, execution information etc.; e.g. PSW (Program Status Word) Register for TriCore Architecture
This register can have predefined fields of single or multiple bits that represent a currently set value (e.g. TriCore has RES, IO and CDC fields). Each field is marked by a vertical square bracket denoting which bits belong to it.
A field can have predefined values, in which case a combo box with these values and their names. Selecting a value updates other fields in the dialog accordingly. If the you changes a certain bit of a field then the value in the combo box is also changed accordingly.
General purpose register example
1. Select the register and double click to open the Modify register dialog.
2. The register can be modified by entering a hexadecimal value or a bitwise value (if hexadecimal value is selected).
