M306NKT-EPB User's Manual
Note on Power Supply to the User System:
Pins Vcc1 and Vcc2 are connected to the user system to observe the voltage. Therefore, the power is not
supplied to the user system from the emulator, design your system so that the user system is powered separately.
(1) The voltage of the user system should be within the operating range of the evaluation MCU.
(2) Do not change the voltage of the user system after turning on the power.
Notes on Internal Flash ROM of the MCU:
In single-chip mode and memory expansion modes, this product downloads a user program to the flash ROM of
an MCU. By checking "Debug Option" in the MCU tab of the MCU setting dialog box of the emulator
debugger, you can disable the operation of the internal flash ROM of the MCU to use the emulation memory of
the PC7501. The maximum operating frequencies are as follows.
(1) "Debug Option " unchecked
Access area: Flash ROM of MCU
Max. operating frequency: 24MHz (0 wait, 1 wait)
(2) "Debug Option " checked
Access area: Emulation memory of the PC7501
Max. operating frequency: 10MHz (0 wait, 1 wait)
Because the number of write/erase cycles of the internal flash ROM of the MCU is limited, it must be replaced
at the end of its service-life.
If the following errors occur frequently when downloading a program, replace the MCU board.
(1) Flash ROM erase error occurred ERROR (16258)
(2) Flash ROM verify error occurred ERROR (16259)
Note on Debugging in Memory Expansion Mode and Microprocessor Mode:
During debugging in memory expansion mode or microprocessor mode with this product, the emulation
memory can be allocated. The emulation memory can be specified up to 4 areas by 4MB in the MAP tab of the
MCU setting dialog box of the emulator debugger.
Each maximum operating frequency is as follows.
- Maximum operating frequency (at 5.0V) 0 wait:
- Maximum operating frequency (at 3.0V) 0 wait:
