Quad-SPI is used to access multi-bit serial flash memory devices for high throughput and low pin count applications. The controller operates in one of three modes: I/O mode, linear addressing mode, and legacy SPI mode. The following table describes the interface signals:

Pin name	Conn. pin	Function	Notes
SPI0_CS0	J1.44	Chip select 0	MIO bank 0, pin 1
SPI0_DQ0	J1.46	1-bit: Master Output 2-bit: I/O0 4-bit: I/O0	MIO bank 0, pin 2
SPI0_DQ1	J1.48	1-bit: Master Input 2-bit: I/O1 4-bit: I/O1	MIO bank 0, pin 3
SPI0_DQ2	J1.50	1-bit: Write protect 2-bit: Write protect 4-bit: I/O0	MIO bank 0, pin 4
SPI0_DQ3	J1.52	1-bit: Hold 2-bit: Hold 4-bit: I/O3	MIO bank 0, pin 5
SPI0_SCLK	J1.54	Serial clock	MIO bank 0, pin 6
