58 Freescale Semiconductor
• Discontinuous conduction mode for 50 Hz and for input voltage higher than half of DC-Bus voltage
— DCM50HzH.s19
• Discontinuous conduction mode for 60 Hz and for input voltage lower than half of DC-Bus voltage
— DCM60HzL.s19
• Discontinuous conduction mode for 60 Hz and for input voltage higher than half of DC-Bus voltage
— DCM60HzH.s19
For reprogramming the microcontroller you have the choice of serial bootloader or MON08 Cyclone. In
the case of the serial bootloader, the bootloader must be programmed into the MCU before uploading the
software application to the MCU by the MON08 Cyclone. After that, reprogramming the application is
quicker than reprogramming by the MON08 Cyclone. For a detailed description of the bootloader
functionality, refer to the application note in Reference [
6]. For a detailed description of the MON08
Cyclone functionality, refer to the application note in Reference [2].
6.2.3 Executing the Application
The application is ready for operation when connected to a power supply.
