3.1.7.3.2. Mapping Parallel Flash Loader II Intel® FPGA IP and Flash Address

The address connections between the Parallel Flash Loader II Intel® FPGA IP and the flash memory device vary depending on the flash memory device vendor and data bus width.
Figure 33.  Flash Memory in 8-Bit ModeThe address connection between the Parallel Flash Loader II Intel® FPGA IP and the flash memory device are the same.
Figure 34.  Flash Memories in 16-Bit ModeThe flash memory addresses in 16-bit flash memory shift one bit down in comparison with the flash addresses in Parallel Flash Loader II Intel® FPGA IP. The flash address in the flash memory starts from bit 1 instead of bit 0.
Figure 35. Micron M28 Flash Memory in 8-Bit ModeThe flash memory addresses in 8-bit flash shifts one bit up. Address bit 0 of the Parallel Flash Loader II Intel® FPGA IP connects to data pin D15 of the flash memory.
Figure 36. Micron M28 Flash Memory in 16-Bit ModeThe address bit numbers in the Parallel Flash Loader II Intel® FPGA IP and the flash memory device are the same.
