The Serial Fast Flash programming interface is based on IEEE Std. 1149.1 “Standard Test
Access Port and Boundary-Scan Architecture”. Refer to this standard for an explanation of terms
used in this chapter and for a description of the TAP controller states.
In this mode, data read/written from/to the embedded Flash of the device are transmitted
through the JTAG interface of the device.
In Serial Fast Flash Programming Mode, the device is in a specific test mode. Only a distinct set
of pins is significant. Other pins must be left unconnected.
