11.1.5.8 Fast Flash Programming Interface (FFPI)

The Fast Flash Programming Interface (FFPI) allows programming the device through a multiplexed fully-handshaked parallel port. It allows gang programming with market-standard industrial programmers.

The FFPI supports read, page program, page erase, full erase, lock, unlock and protect commands.

The FFPI is enabled and the Fast Programming mode is entered when TST and PA3 and PA4 are tied low.
