DemoKit-LF3 User’s Manual
Some of the DemoKit-LF3 components are free for user application hardware and software. Refer to the
78K0/LF3 device user’s manual to obtain information about electrical specifications for the available I/O
ports before connecting any external signals to the DemoKit-LF3 board.
2.1 SW1 and SW2 configuration switches
The settings of SW1 and SW2 specify the DemoKit’s operating modes.

2.1.1 IDK78K0-TK on-board debugging mode
2.1.2 WriteEZ3 flash programming mode
2.1.3 QB-MINI2 on-chip debugging / normal execution
2.2 SW4 reset button
The SW3 reset button activates the power-on reset and controls the microcontroller’s reset input signal.
In this mode, you can perform on-board debugging via the default USB/UART connection to the
host computer, without the use of additional debugging hardware. Standard commands for flash
programming, downloading programs, executing code, single-stepping through programs, setting
breakpoints, and manipulating memory are available.
In WriteEZ3 mode, you can reprogram the microcontroller’s internal flash memory using NEC
Electronics’ WriteEZ3 flash programming software and the default USB/UART connection to the
host computer.
In QB-MINI2 mode, you can connect the QB-MINI2 on-chip debugging emulator (available
separately) to the DemoKit-LF3 board and use the microcontroller’s on-chip debugging function.
When the on-chip debugging emulator is not connected to the board,
normal execution and executes the user program stored in flash memory.
