      In the slave mode, the SPISTE signal should be asserted low at least 0.5t
      c(SPC)
      (minimum) before the valid SPI clock
      edge and remain low for at least 0.5t
      c(SPC)
      after the receiving edge (SPICLK) of the last data bit.

      The MASTER / SLAVE bit (SPICTL.2) is cleared and the CLOCK PHASE bit (SPICTL.3) is cleared.
      t
      = SPI clock cycle time = LSPCLK/4 or LSPCLK/(SPIBRR + 1)
      Internal clock prescalers must be adjusted such that the SPI clock speed is limited to the following SPI clock rate:
      Master mode transmit 25-MHz MAX, master mode receive 12.5-MHz MAX
      Slave mode transmit 12.5-MHz MAX, slave mode receive 12.5-MHz MAX.
      The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPICCR.6).
