Description
Parallel Fast Flash Programming
Device Configuration
The Fast Flash Programming Interface provides solutions for high-volume programming using a
standard gang programmer. The parallel interface is fully handshaked and the device is consid-
ered 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. Other pins must be left unconnected. The Fast Flash Programming Interface is
enabled and the Fast Programming Mode is entered when TST, PA0, PA1 are set to high, PA2
and PA3 are set to low and NRST is toggled from 0 to 1.
