Zynq-7000 AP SoC - How do I send less than four bytes to the TxFIFO in the Quad-SPI controller?

説明

Whenever I write less than four bytes to the TxFIFO (TXD0), the transmit does not complete.Why is this?

ソリューション

When sending less thanfour bytes, you must use TXD[1-3] instead of TXD0. Thisis described in the Register Overview section of the Quad SPI controller chapter in the Zynq-7000 Technical Reference Manual (UG585).
