R
The following guidelines are recommended when storing user data in the In-System Flash
(ISF) memory.
1.
2.
See the
FPGA and for both addressing modes.
Do not intermix user data with the last page of FPGA configuration bitstream data.
Intermixing user data and configuration data makes updating the FPGA bitstream
more difficult.
If using the
