T89C51RD2
Exernal Host with
Specific Protocol
Communication
On the above diagram, the on-chip bootloader processes are:
•
The purpose of this process is to manage the communication and its protocol between
the on-chip bootloader and a external device. The on-chip ROM implement a serial pro-
tocol (see section Bootloader Protocol). This process translate serial communication
frame (UART) into Flash memory acess (read, write, erase ...).
•
Several Application Program Interface (API) calls are available for use by an application
program to permit selective erasing and programming of Flash pages. All calls are made
through a common interface (API calls), included in the ROM bootloader. The program-
ming functions are selected by setting up the microcontroller’s registers before making a
call to a common entry point (0xFFF0). Results are returned in the registers. The pur-
pose on this process is to translate the registers values into internal Flash Memory
Management.
•
This process manages low level access to Flash memory (performs read and write
access).
