at address zero depends on the combination of the TST pin and PA0 to PA3 pins.
shows the contents of the ROM and the program available at address zero.
The Fast Flash Programming Interface programs the device through a serial JTAG interface or 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 Fast Flash Programming Interface is enabled and the Fast Programming Mode is entered
when the TST pin and the PA0 and PA1 pins are all tied high, while PA2 and PA3 are tied low.
Table 8-1.
The SAM-BA Boot Assistant is a default Boot Program that provides an easy way to program in
situ the on-chip Flash memory.
The SAM-BA Boot Assistant supports serial communication through the DBGU or through the
USB Device Port.
