你可以把它理解为一个Octo SPI接口内部通过逻辑划分成两个QSPI通道，这样可以同时传输两个独立的数据流。
thecreation of an STM32H7 Value Linewith a lot less Flash so designers that require external QuadSPI for graphic-intensive applications don’t have to pay for embedded storage they will never use. Today, the STM32H750 is the first Value Line MCU commercially available in the STM32H7 series...

3. Qual SPI 与Dual SPI类似,也是针对SPI Flash,Qual SPI Flash增加了两根I/O线(SIO2,SIO3),目的是一个时钟内传输4个bit 所以对于SPI Flash,有标准spi flash,dual spi , qual spi 三种类型,分别对应3-wire, 4-wire, 6-wire,在相同clock下,线数越多,传输速率越高。
