15 The QUP core is an AHB slave that provides a common data path (an output FIFO
16 and an input FIFO) for serial peripheral interface (SPI) mini-core.
18 SPI in master mode supports up to 50MHz, up to four chip selects,
19 programmable data path from 4 bits to 32 bits and numerous protocol variants.
