PROGRAMMING EXTERNAL E2P
- Run FLIP
- Select part at8xc5122
- Establish a USB communication
---> Results : if a Software Security Error windows comes up, just click OK. This
windows just warns that the part security bit is activated. In this case, an erase
operation is mandatory before programming the part
- Select Erase, Blank Check, Program and Verify options
- Load the user code into FLIP buffer
- Edit FLIP buffer
- Configure the area from 07FFD to 07FFF according to the wanted options (Refer
to bootloader datasheet). A common configuration is :
07FFD = 08h
07FFE = MSB (user code size)
07FFF = LSB (user code size)
- Select Whole buffer in buffer options menu

AT89STK-03 Hardware User Guide
Comments
- Setting hardware condition
P3.7=0 during power on or reset
will force the bootloader to enter
in ISP mode with FLIP
- DRV bootloader supports E2P
write functions to program the
external E2P.
- The area from 07FFD to 07FFF
can be configured by means of
FLIP’s GUI. It is recommended
to check the configuration by
editing the FLIP buffer from
07FFF to 07FFF
