I want to initiate the serial downloader through the SPI port, how can I do
A bootloader mode is implemented on the ADuC834 allowing re-programming of the
program memory using any peripherals or any protocol that the user wishes.
To download to this space you will have to write your own downloader in the
bootloader space (E000H -> F7FFh of flash/EE program memory) to download to the
rest of the
flash/EE program memory. The downloader can use any means to download,
parallel, SPI, I2C,
UART or any other protocol you wish.
