Notes on Debugging in CPU Rewrite Mode:
Note on Software Breaks:
Note on Downloading Programs:
Notes on Service-Life of the MCU’s Internal Flash ROM:
Note on Voltage Detect Circuit:
To debug a program in CPU rewrite mode, check the box “Debug the program using the CPU Rewrite Mode” in
the MCU tab of the Init dialog box. When you do not debug a program in CPU rewrite mode, uncheck the box.
When you debug a program in CPU rewrite mode, the block 0 area (FFF000h--FFFFFFh) must not be rewritten.
Otherwise, the emulator will be out of control.
When debugging in CPU rewrite mode is enabled, you cannot use the following functions.
Do not use the following functions to the rewrite control program area (from setting CPU rewrite mode select
bit to releasing it). If any of these are used, malfunctions may occur (e.g. The emulator cannot shift to CPU
rewrite mode or contents of ROM cannot be read our properly.).
A software break generates a break interruption by forcibly inserting a BRK instruction “08h” instead of an
instruction code. Therefore, when referencing the result of a trace in bus mode, “08h” is displayed for the
instruction fetch address where a software break is set.
When you download a program to an internal ROM area and set software breaks, the main clock operates in
divide-by-8 mode. Keep it in mind when you specify a watchdog timer refresh interval.
With the M30850T2-CPE, programs are downloaded to the MCU’s flash ROM when debugging in single-chip
mode or memory expansion mode. Because the number of write/erase cycles of this ROM is limited, the ROM
must be replace when at the end of its service-life.
If the following errors occur frequently during program download, replace the MCU board.
With the M30850T2-CPE, as the power voltage cannot be change after powering on the user system, the
voltage detect circuit (voltage down detect interrupt and hardware reset 2) cannot be used with this product.
