API CALL 89C51CC02CA

Mar 02, 2009 0 Replies

Hi @all!



I'm using an Atmel 89C51CC02CA. I'm trying to use the Api-functions, implemented in the bootloader. I understood that i first have to write my values to the api_command, api_value and api_dptr (dpl and dph), which is placed in the controllers ram. Then i have to call the codeadress 0xFFF0h.


But doing so leads to a reset of the controller. i tried different commands, the result is the same. So i guess the code-adress is wrong?


watchdog is disabled, so are the interrupts. oh, and the ENBOOT-bit is set...


Thank you for any ideas!
