MSS ISP (SmartFusion2 Only)
UG0451 User Guide Revision 7.0 26
The following tables describe the ISP response and the corresponding programming service status
codes.
An authentication error might occur in any frame of the bitstream. See Table 19, page 33 and Table 20,
page 33 for details on error codes. If the MODE is PROGRAM, and there is a failure, the device might be
left in an inconsistent and non-operational state. Therefore, the user application must only commit the
bitstream for programming after successful authentication, and thus the integrity of the bitstream is
validated.
After the programming operation is complete, an internal reset is generated for the new design to take
effect, and the completion handler cannot be called by the system services driver. No exit codes are
reported, which is normal and expected. The completion of the programming must be realized by
observing the new design functioning immediately after programming. If there is a problem, and the part
did not reset, then you can observe the completion handler.
Note: The isp_completion_handler function must be implemented by the application program, and it is
called by the system services driver when an ISP operation initiated by a call to
MSS_SYS_start_isp() completes.
