T89C51CC02 CAN Bootloader
The T89C51CC02 Bootloader facilitates In-System Programming and In-Application
Programming.
The ISP allows the user to program or reprogram a microcontroller on-chip Flash memory with-
out removing it from the system and without the need of a pre-programmed application.
The CAN bootloader can manage a communication with a host through the CAN network. It can
also access and perform requested operations on the on-chip Flash memory.
In-Application Programming (IAP) allows the reprogramming of a microcontroller on-chip Flash
memory without removing it from the system and while the embedded application is running.
The CAN bootloader contains some Application Programming Interface routines named API rou-
tines allowing IAP by using the user’s firmware.
This section describes the different parts of the bootloader. Figure 1 shows the on-chip boot-
loader and IAP processes.
