Flash and ISP specification
Figure 6-2. Boot Process
Note:
•
The ISP_FORCE GP fuse bit is set to 1 by the ISP on each ISP command received and it is
set to 0 by the ISP when a request to start the application is received. That means that after
a command has been sent using BatchISP, the user will not be able to start his application
until he has issued a START operation to BatchISP. This behavior ensures the consistency
of programmed data thanks to a non-volatile programming session.
