4 – SmartFusion Programming
In-System Programming
SmartFusion devices have three separate flash areas that can be programmed:
There are essentially three methodologies for programming these areas:
Programming, whether ISP or IAP methodologies are employed, can be done in two ways:
In-System Programming is performed with the aid of external JTAG programming hardware.
describes the JTAG programming hardware that will program a SmartFusion device and
defines the JTAG pins that provide the interface for the programming hardware.

The JTAGSEL pin selects the FPGA TAP controller or the Cortex-M3 debug logic. When JTAG SEL is
asserted, the FPGA TAP controller is selected and the TRSTB input into the Cortex-M3 is held in a reset
state (logic 0), as depicted in
