20. Fast Flash Programming Interface (FFPI)
20.1
6222F–ATARM–14-Jan-11
Overview
The Fast Flash Programming Interface provides two solutions - parallel or serial - for high-vol-
ume 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. The serial inter-
face uses the standard IEEE 1149.1 JTAG protocol. It 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 not designed for in-situ programming.
