1.2. Description of the Altera Serial Flash Controller
The Intel® Serial Flash Controller with Avalon interface allows Nios® II processor systems to access Intel® EPCQ flash memory, which supports standard, quad and single- or dual-I/O mode. The Nios® II processor SBT supports the Nios® II booting from the Intel® Serial Flash Controller. In addition, a Nios® II hardware abstraction layer (HAL) driver is available for the Intel® Serial Flash Controller that allows an application to read, write, or erase flash.
