21.7.2 Features
500
(1) Interrupt support
(2) Standard self programming flow
Instructions cannot be fetched from the flash memory during self programming. Conventionally, therefore, a
user handler written to the flash memory could not be used even if an interrupt occurred. With the
V850ES/SA2 and V850ES/SA3, however, a user handler can be registered to an entry RAM area by using a
library function, so that interrupt servicing can be performed by internal RAM or external memory execution.
The entire processing to rewrite the flash memory by flash self programming is illustrated below.
If a security setting is not performed, flash information setting processing does not have to be executed.
Flash environment initialization processing
Flash information setting processing
Flash environment end processing
Flash memory manipulation
