(1) The Controller bit (SPIGCRx.0) is cleared ( where x = 0 or 1 ).
(2) The CLOCK PHASE bit (SPIFMTx.16) is either cleared or set for CLOCK PHASE = 0 or CLOCK PHASE = 1 respectively.
(3) tc(MSS_VCLK) = main subsystem clock time = 1 / f(MSS_VCLK). For more details, refer to the device Technical Reference Manual.
(4) When the SPI is in Peripheral mode, the following must be true: For PS values from 1 to 255: tc(SPC)S ≥ (PS +1)tc(MSS_VCLK) ≥ 25 ns, where PS is the prescale value set in the SPIFMTx.[15:8] register bits.For PS values of 0: tc(SPC)S = 2tc(MSS_VCLK) ≥ 25 ns.
(5) The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPIFMTx.17).
