WebThe Quad-SPI is a serial interface that allows the communication on four data lines between the host and an external Quad-SPI memory. The QSPI supports the traditional SPI (serial peripheral interface) as well as the dual-SPI mode which allows to communicate on two lines. QSPI uses up to six lines in quad mode.
