AT89C51CC03 CAN Bootloader
ISP allows the user to program or reprogram a microcontroller’s on-chip Flash memory through
the CAN network without removing it from the system and without the need of a pre-pro-
grammed application.
This section describes how to start the CAN bootloader and the higher level protocol over the
CAN.
The bootloader can be activated in two ways:
•
•
The Hardware conditions (EA = 1, PSEN = 0) during the RESET# falling edge force the on-chip
bootloader execution. In this way the bootloader can be carried out whatever the user Flash
memory content.
As PSEN is an output port in normal operating mode (running user application or bootloader
code) after reset, it is recommended to release PSEN after falling edge of reset signal. The hard-
ware conditions are sampled at reset signal falling edge, thus they can be released at any time
when reset input is low.
