Sundance SMT329 - Manual (Page 14)

The map itself is embedded in a normal text file, and the whole text file is stored in the flash,
so that the map can be accompanied by any descriptive text, up to a maximum file size of 64K
bytes. The map is identified in the text by the keyword “SMT329MAP
”.
The SMT329 flash can be programmed from either the VME bus or by a TIM in either slot 1
or 4. The map is loaded from the flash into the Spartan3 fpga by the CPLD, immediately after
the SMT329 power is stable following switch on. The map can not be loaded at any other
time. The map must load without error for the cross bar switch to work correctly. The
Spartan3 performs the following data validation checks before enabling the switch:
1. All entries are in the range 0 to 13.
2. No entry is the same.
If either of these criteria are not met, the switch will not be enabled.
