How XC17S10PD8C Works: Configuration Modes
Master Serial Configuration Mode
When the Spartan device operates in Master Serial mode, it generates a configuration clock that drives the FPGA PROM. Following the rising clock edge, data appears on the PROM DATA output pin connected to the Spartan device DIN pin. The FPGA automatically generates the correct number of clock pulses required for complete configuration, then disables the PROM after successful configuration.
Slave Serial Configuration Mode
In Slave Serial mode operation, both the XC17S10PD8C PROM and the Spartan FPGA device receive clock signals from an external source. This mode provides synchronized configuration control for systems requiring external timing management.
