The IAP allows to reprogram a microcontroller on-chip Flash memory without removing it from
the system and while the embedded application is running.
The user application can call Application Programming Interface (API) routines allowing IAP.
These API are executed by the bootloader.
To call the corresponding API, the user must use a set of Flash_api routines which can be linked
with the application.
Example of Flash_api routines are available on the Atmel web site on the software application
note:
C Flash Drivers for the T89C51CC01CA for Keil Compilers
The Flash_api routines on the package work only with the CAN bootloader.
The Flash_api routines are listed in Appendix-B.
The application selects an API by setting the 4 variables available when the Flash_api library is
linked to the application.
These four variables are located in RAM at fixed address:
•
•
•
•
All calls are made through a common interface “USER_CALL” at the address FFC0h.
The jump at the USER_CALL must be done by LCALL instruction to be able to comeback in the
application.
Before jump at the USER_CALL, the bit ENBOOT in AUXR1 register must be set.
The interrupts are not disabled by the bootloader.
Interrupts must be disabled by user prior to jump to the USER_CALL, then re-enabled when
returning.
Interrupts must also be disabled before accessing EEPROM data then re-enabled after.
The user must take care of hardware watchdog before launching a Flash operation.
For more information regarding the Flash writing time see the T89C51CC01 datasheet.
