3.7
The emulator has the event point function to support breakpoints of the following three types.
Software breakpoints: Execution of the user program stops when the instruction at the specified address is
fetched. Up to 255 software breakpoints can be set. Any content at the specified address is replaced by a break
instruction (a dedicated instruction for use with the emulator). The software breakpoint cannot be set in the
write-protected area such as ROM area or flash memory area on the user system. The user can set a software
breakpoint in the [Editor] or [Disassembly] window.
On-chip breakpoints: These break functions built in the MCU. Conditions on the address bus, data bus,
bus/area, and satisfaction count can be set. The on-chip breakpoint can be set even in the ROM area or flash
memory area on the user system. It is also possible to set a sequential breakpoint consisted of several on-chip
breakpoints. The user can set an on-chip breakpoint in the [Editor] or [Disassembly] window.
On-emulator breakpoints: On-emulator break functions are implemented by dedicated hardware in the
E6000H station. Conditions on the address bus, data bus, bus/area, external probe signals, external interrupt
signals, and satisfaction count can be set. As the emulator hardware provides this function, several cycles may be
required until a break occurs after satisfaction of a condition.
Software, on-chip, and on-emulator breakpoints can be set in the [Event] window.
Select [View -> Code -> Eventpoints] or click the [Eventpoints] toolbar button (
The [Event] window has the following three sheets:
