21. Fast Flash Programming Interface (FFPI)
21.1 Description
The Fast Flash Programming Interface (FFPI) provides parallel high-volume programming using a standard gang
programmer. The parallel interface is fully handshaked and the device is considered to be a standard EEPROM.
Additionally, the parallel protocol offers an optimized access to all the embedded Flash functionalities.
Although the Fast Flash Programming Mode is a dedicated mode for high volume programming, this mode is not
designed for in-situ programming.
21.2 Embedded Characteristics

 Enables Control of Lock Bits and General-purpose NVM Bits
 Enables Security Bit Activation
 Disabled Once Security Bit is Set
 Parallel Fast Flash Programming Interface
 Provides an 16-bit Parallel Interface to Program the Embedded Flash
 Full Handshake Protocol
