FPGA configure problem

EPCS64 is only using as configuration mode. Configuration schemes are discussed in the respective FPGA hardwore handbook and the Altera configuration handbook.

The AS configuration device can be programmed from a MCU by directly interfacing CS, SCK, DI and DO, also FPGA nCE must be driven high to disable FPGA access to the device. Quartus *.rbf files can be directly programmed to the AS memory, the data bit order has to be reversed related to the SPI standard.
