Breakpoints Window
Invoke the Breakpoints
Window from the
Debug Menu.
You have to stop the
program running, to get
access to this dialog.
Modify existing
breakpoints and add new
breakpoints via this
dialog. Enable/disable
breakpoints using the
checkbox in the
Current Breakpoints list. Double-click on an existing breakpoint to modify its
definition.
Define a breakpoint by entering an Expression. Depending on the expression
entered, one of the following breakpoint types is defined:
An Execution Breakpoint (E) is defined when the expression specifies a
code address. This breakpoint is triggered when the specified code address is
reached. The code address must refer to the first byte of a microcontroller
instruction.
An Access Breakpoint (A) is defined when the expression specifies a
memory access (read, write, or both) instruction. This breakpoint is triggered
when the specified memory access occurs. You may specify the number of
bytes or objects (based on the expression) which trigger the breakpoint.
Expressions must reduce to a memory address and type. Operators (&, &&,
<. <=. >, >=, = =, !=) may be used to compare values before the Access
Breakpoint triggers and halts program execution or executes the Command.
A Conditional Breakpoint (C) is defined when the expression specifies a
true/false condition and cannot be reduced to an address. This breakpoint is
triggered when the specified conditional expression is true. The conditional
expression is recalculated after each instruction. Therefore, program
execution may slow down considerably.
