(1) The MASTER bit (SPIGCRx.0) is set and the CLOCK PHASE bit (SPIFMTx.16) is set ( where x = 0 or 1 ).
(2) tc(MSS_VCLK) = master subsystem clock time = 1 / f(MSS_VCLK). For more details, see the Technical Reference Manual.
(3) When the SPI is in Master mode, the following must be true: For PS values from 1 to 255: tc(SPC)M ≥ (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)M = 2tc(MSS_VCLK) ≥ 25 ns.
(4) The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPIFMTx.17).
(5) C2TDELAY and T2CDELAY is programmed in the SPIDELAY register
