ESAS E1 E20 Emulator Section 6 Notes on Usage 6 8 Break Functions 6 8 1 Notes on Setting Break Points e S W break points replace the instructions at the corresponding addresses They cannot be specified in the area other than the on chip ROM and on chip RAM e During stepped execution specifications of S W break points and on chip breakpoints are invalid e When execution is restarted from the address where it stopped at a breakpoint S W breakpoints or pre PC execution breakpoints the actual instruction at the address must be executed as a single step before further execution continues Operation is thus not in real time Note that any event that occurred in this single step execution is cleared when the program is executed thereafter Therefore if a trace or performance start event trigger is set in this step neither trace acquisition nor performance measurement begins until the event occurs again The same applies to break and trace start combinational events so that any event that occurred in a step is not added to AND cumulative nor does it cause a state transition e On chip breakpoints cannot be set while the emulator is in a power down mode e If an on chip breakpoint has been set through the On chip Break points column of the Editor window in a power down mode the Output window shows either of the messages given below In the sleep mode The internal clock is halted because the MCU is in the sleep mode In
