The Disassembly view provides four columns for breakpoints and PC indicator, address, opcode, and disassembly string.
If your target model has TrustZone® support, disassembly breakpoints from all worlds appear in the first column. The filled red circles indicate a breakpoint in the world in the disassembly view, and unfilled red circles indicate breakpoints in other worlds.
The green arrow indicates the actual position of the PC.
To display the whole disassembly in a help bubble, move the cursor over a disassembly line. This function is useful if the complete disassembly string does not fit horizontally into the view.

Mapping source lines to the disassembly listing
To highlight in blue the corresponding addresses in the disassembly view, click the left-most column in the source view. The highlighting indicates the disassembly instructions to which the respective source statement maps.
