Virtex Configuration - Can devices be daisy-chained in SelectMAP mode?
Daisy-chaining of devices is available in the serial modes. Is it possible in SelectMAP mode?
No, daisy-chaining is not possible in SelectMAP mode. The BUSY signal used in SelectMAP is the same pin as DOUT, which would normally provide downstream devices with data.
However, parallel loading is possible. For more information, please refer to (Xilinx XAPP138), Virtex FPGA Series Configuration and Readback.
