SPISTE
A. In the master mode, SPISTE goes active 0.5 tc(SPC) (minimum) before valid SPI clock edge. On the trailing
end of the word, the SPISTE will go inactive 0.5 tc(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 non-FIFO modes.
