Working with BreakpointsSimple Break if X, when Y is True dialog box interface componentsThe Simple Break if X, when Y is True dialog box (see Figure 4-12 on page 4-37)contains the following fields:Enter Address Expression to Break onChoose the type of breakpoint that you want to set. The options are:• SW Instr• HW Instr• HW Access• HW Read• HW Write.Specify the location where the breakpoint is to be set. This can be:• a specific line number in the source code, with or without a modulename prefix (see Qualifying breakpoint line number referenceswith module names on page 4-7)• a specific address or address range (see Specifying address rangeson page 4-7)• a function entry (see Specifying the entry point to a function onpage 4-8).The breakpoint unit triggers if the PC equals the corresponding address,or falls within the specified address range. For example, Proc_3.When expression is TrueThe expression to test. This must give a True or False value as the result,or example, Run_Index==10.You can enter values directly in these fields, or you can click the drop-down arrow tothe right of the fields to choose from a list browser (see List browser dialog boxes onpage 8-2), select from your personal Favorites List (see Favorites categories used byRealView Debugger features on page 8-32), or select from a list of previously-usedexpressions.4.7.4 Setting conditional hardware breakpointsAlthough hardware breakpoints can have conditions that are controlled in hardware,they are not conditional breakpoints in RealView Debugger. RealView Debuggerrecognizes a breakpoint as conditional only when a condition qualifier is assigned to thebreakpoint. Condition qualifiers are software conditions that are controlled byRealView Debugger.4-38 Copyright © 2002-2005 ARM Limited. All rights reserved. ARM DUI 0153G
