(2) Interrupt support
The entire processing to rewrite the flash memory by flash self programming is illustrated below.
A user handler written to the flash memory cannot be used even if an interrupt occurred during flash function
execution.
Therefore, in the V850E/IF3 and V850E/IG3, to use an interrupt during flash function execution, processing
transits to the specific address
the user interrupt servicing at the specific address
Note NMI interrupt:
Maskable interrupt: Start address of internal RAM + 4 addresses
Flash environment initialization processing
Flash environment end processing
Flash memory manipulation
Internal verify processing
End of processing
Erase processing
Write processing
All blocks end?
