Description
Parallel Fast Flash Programming
Device Configuration
The Fast Flash Programming Interface provides parallel high-volume programming using a stan-
dard 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.
In Fast Flash Programming Mode, the device is in a specific test mode. Only a certain set of pins
is significant. The rest of the PIOs are used as inputs with a pull-up. The crystal oscillator is in
bypass mode. Other pins must be left unconnected.
