3.1.1 On-Board Debug Mode (TK-78 debugging)
Within this mode On-Board debugging is enabled. By using this mode no additional debug hardware like
the QB-MINI2 On-Chip debug emulator is needed. The debugging is done via the default USB/UART
connection to the Host computer. All standard debug function are available in the On-Board debug mode
like FLASH programming / downloading, code execution, single stepping, breakpoints, memory
manipulation etc.
3.1.2 FPL3(
WriteEZ3
) Mode (FLASH programming mode)
This mode allows to reprogram the internal FLASH memory of the 78K0/LF3 device by using the
WriteEZ3 FLASH programming software. Within this mode FLASH programming is done by using the
default USB/UART connection to the Host computer.
3.1.3 QB-MINI2 Mode (OCD debugging / Normal execution mode)
Within this mode the QB-MINI2 On-Chip debug emulator can be connected to the
78K0/Lx3 - See it!
board in order to use On-Chip debug function of the 78K0/LF3 device.
Additional, when no QB-MINI2 On-Chip debug emulator is connected to the
78K0/Lx3 - See it!
board
the
78K0/LF3 device starts within normal execution mode and the user program stored in the FLASH
memory is executed.
