Can a SPI slave interrupts the IMX6 solo on the SPI bus

Hi ,


In my target custom board , a SPI device is interfaced with IMX6 solo over the SPI bus.  Now as per my understanding ,

SPI controller over the IMX6  as a master is the clock generator on the SPI bus . So it will  source the clock during the \

read and write cycles over the SPI bus. So SPI controller will only poll the data from the SPI slave . SPI slave cannot

gives the interrupt to the SPI controller to read the data. But as I see in the reference manual of IMX6 solo , chapter 3 "Interrupts and DMA"  table 3-1  , interrupts number 63 is dedicated for  eCSPI1 . How this interrupt will work ?

Please help me to understand.
