Step 2: In the Debug Perspective, Open the breakpoint dialog: View->Breakpoints
Step 3: Use the pulldown to select a new breakpoint and choose Hardware Watchpoint
Step 4: Specify the address you want to watch, and if it is a read or write access.
Step 5: Right click on the watchpoint and select Properties.
Step 6: From this dialog box you can further configure the watchpoint:
- Configure a data read/write of a particular value from the address.
- Configure the size of the data
- Configure a mask value (bits that will be ignored)
