Overview

After the Monitor Program is written to the MCU and the Monitor Program communicates with the Debugger, the user program can be debugged. 

  • Software for on-chip debugging on High-performance Embedded Workshop or KD3x.
  • The Monitor Program is automatically written to the MCU when the Debugger is started up. Therefore, there is no need to write the Monitor Program to the MCU using a flash programmer.
  • You can debug by the same pin handling as Standard Serial I/O Mode 2 for the flash programmer.
  • Initialize (erase) the user program area using a flash programmer before using the Monitor Program.
  • Use RS-232C for communication between the Debugger and the Monitor Program.

Operating Environment

The operating environment depends on your debugger.

Note

ID Check Function

The ID check function, which provides protection against accidentally erasing the user program, is supported except in R8C/10 and R8C/11 Groups with Boot Program Version 0.90. This function checks the addresses in which the ID code is stored when the Debugger is started up, and executes the debugging program (erase internal ROM and download Monitor Program) only when the ID code is "all FFh".
When the ID code is not "all FFh", the Debugger displays a time-out error and KD30 will not operate (internal ROM will not be erased and Monitor Program will not be downloaded).

ID Code at Debug Completion

[R8C/10 and R8C/11 Groups Boot Program Ver.0.90]
The Monitor Program sets ID3, ID4, and ID6 to "00h". All other codes are set according to the ID code of the user program. For example, if the user program ID code is set to "all FFh", the codes will be as follows.
Therefore, we recommend setting the user program ID code to "all 00h" .

  ID1: FFh (address 0FFDFh)
ID2: FFh (address 0FFE3h)
ID3: 00h (address 0FFEBh)
ID4: 00h (address 0FFEFh)
ID5: FFh (address 0FFF3h)
ID6: 00h (address 0FFF7h)
ID7: FFh (address 0FFFBh)

[R8C/10 and R8C/11 Groups Boot Program Ver.1.00 or later and Other Groups of R8C Family]
The Monitor Program sets ID1 through ID7 to "all FFh". Therefore, regardless of what the ID code is set to in the user program, this will not be reflected in the final outcome. Accordingly, after debug is completed, the ID code will always be "all FFh".
