SPISTE
A. In the master mode, SPISTE goes active 0.5tc(SPC) (minimum) before valid SPI clock edge. On the trailing end of the
word, the SPISTE will go inactive 0.5tc(SPC) after the receiving edge (SPICLK) of the last data bit, except that SPISTE
stays active between back-to-back transmit words in both FIFO and nonFIFO modes.
