•
The FM0 can be program by both parallel programming and Serial In-System-Program-
ming (ISP) whereas FM1 supports only parallel programming by programmers. The ISP
mode is detailed in the "In-System-Programming" section.
All Read/Write access operations on Flash Memory by user application are managed by
a set of API described in the "In-System-Programming" section.
