The power supply can also be applied using the QB-78K0MINI on-chip debugging (OCD) emulator.
Close jumper JP2 to apply power from the QB-78K0MINI.
Jumper JP3 controls the MCU’s clock supply. Closing JP3 applies an external frequency of 6 MHz to
the MCU’s P122/X2 clock input pin. Opening JP3 allows an external oscillator to be used when pad X1
(not assembled) of the kit is equipped with a corresponding oscillator.
The board’s different operating modes can be set using SW1 switches S1–S4.
3.4.1
SW1 switch S1 controls the DemoKit-LG2 board’s operating mode. Setting SW1/S1 to ON allows you
to reprogram the MCU’s internal flash memory using the FPL3 flash programming software.
