4.2 Note of Debugging
CHAPTER 4 CAUTIONS
- Operation after target system power application
After power application, a program will be executed for the target device mounted in the target system when
reset is released. However, with the QB-RL78L1C, the program does not start until an operation to start
execution is performed after the program is downloaded using the debugger.
- Relation between Standby function and Break function
The break is interrupt function of CPU. The standby mode is released by the break for using the following
debug function.
- Forced break function.
- Step execution of the standby instruction (Stops user program after executing instruction)
- Pseudo real-time RAM monitor function (Break When Readout)
- Pseudo Dynamic Memory Modification function (Break When Write)
- Breakpoint setting during executing of the user program.
- Invalid memory access detection function (IAW)
The behavior when detecting an invalid memory access is different between target device and emulator.
Target device : Reset
QB-RL78L1C : Fail-safe break
- CRC calculation function
When using the CRC calculation function, do not set software breaks. Differing calculation results will be output.
