If SPI0_ENA is asserted immediately such that the transmission is not delayed by SPI0_ENA.
(8)
In the case where the master SPI is ready with new data before SPI0_SCS assertion.
(9)
This delay can be increased under software control by the register bit field SPIDELAY.C2TDELAY[4:0].
(10) If SPI0_ENA was initially deasserted high and SPI0_CLK is delayed.

These parameters are in addition to the general timings for SPI slave modes
(Table 6-65).(2)
P = SYSCLK2 period; M = tc(SPC)M (SPI master bit clock period)
(3)
Figure shows only Polarity = 0, Phase = 0 as an example. Table gives parameters for all four slave clocking modes.
