Monitor Debuggers
This tool allows the user to debug a user program by writing a Monitor Program to the MCU. RS-232 is used for UART communication between the PC and the MCU.
System Configuration
This is the system configuration of the monitor debugger system below. For UART communication through RS232, please use a commercial communication cable or Renesas MF Ten Nine Cable (M3A-0652CBL). When using a commercial communication cable, carry a RS232 transceiver to the target board. When using a Renesas MF Ten Nine Cable (M3A-0652CBL), it is not necessary to carry RS232 transceiver to a target board since it is built in the cable.
Preparations
- PC with Serial Port
- Communication Cable
- Target Board, Power Supply
- Flash Programmer (for writing the monitor program to the MCU)
* R8C UART Monitor Program (Please see below.) does not require a flash programmer. - Monitor Program
* You can download the monitor programs from M32C M16C UART Monitor Program page (Please see below.).
R8C UART Monitor Program doesn't require the monitor program. - Debugger
* You can download the debuggers from M32C M16C UART Monitor Program and R8C UART Monitor Program pages.
Monitor Program
Two methods are provided for writing the monitor program to the MCU.
[M32C M16C UART Monitor Program]
| Target Devices: | M16C/62A(M), M16C/80 and M32C/83 Groups |
| The user writes this monitor program to the MCU using a flash programmer (ex. M16C Flash Starter). After writing to the MCU, the Debugger is used to download the user program. | |
| Target Devices: | R8C Family |
| This Monitor Program is automatically written to the MCU when the Debugger is started up. After the debugger is started up, the debugger is used to download the user program. | |
Comparison of M32C M16C UART Monitor Program and R8C UART Monitor Program
| Item | M32C M16C UART Monitor Program | R8C UART Monitor Program |
| Link with user program | No | No |
| Priority program | Monitor Program | Monitor Program |
| User writes Monitor Program to MCU | Necessary | Not necessary |
| Continues user program execution after stopping Debugger? | No (user program also stops) | No (user program also stops) |
Lineup:
M32C M16C UART Monitor Program
Monitor Program for M32C/80, M16C/80 and M16C/60 Serieses. It is necessary for a user to write the Monitor Program to the MCU using a flash programmer.
R8C UART Monitor Program
Monitor Program for R8C Family. The Monitor Program is automatically written to the MCU when the Debugger is started up.
