Addressing Mode
To access the EPCQ-L256, EPCQ-L512, or EPCQ-L1024 memory, you must use the 4-byte addressing mode. In 4-byte addressing mode, the address width is 32-bit. To enable the 4-byte addressing mode, you must execute the 4BYTEADDREN operation. This addressing mode takes effect immediately after you execute the 4BYTEADDREN operation and remains active in the subsequent power-ups. To disable the 4-byte addressing mode, you must execute the 4BYTEADDREX operation.
Note: If you are using the Intel® Quartus® Prime software or the SRunner software to program the EPCQ-L256, EPCQ-L512, or EPCQ-L1024 device, you do not need to execute the 4BYTEADDREN operation. These software tools automatically enable the 4-byte addressing mode when programming the device.
