Full Quad SPI Modes (QPI)
The EN25F20A also supports Full Quad SPI Mode (QPI) function while using the Enable Quad
Peripheral Interface mode (EQPI) (38h). When using Quad SPI instruction the DI and DO pins become
bidirectional I/O pins; DQ
0
and DQ
1,
and the WP# and HOLD# pins become DQ
2
and DQ
3
respectively.
