(1)
The MASTER bit (SPIGCR1.0) is set and the CLOCK PHASE bit (SPIFMTx.16) is set.
(2)
tc(VCLK) = interface clock cycle time = 1 / f(VCLK)
(3)
For rise and fall timings, see the Table 3-5.
(4)
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(VCLK) ≥ 40ns, where PS is the prescale value set in the SPIFMTx.[15:8] register bits.
For PS values of 0: tc(SPC)M = 2tc(VCLK) ≥ 40ns.
The external load on the SPICLK pin must be less than 60pF.
(5)
The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPIFMTx.17).
(6)
C2TDELAY and T2CDELAY is programmed in the SPIDELAY register
