rising edge from master, 4-pin mode, polarity = 0, phase = 0
Delay time, slave assertion of SPI_EN active to first SPI_CLK

Delay time, slave assertion of SPI_EN active to first SPI_CLK
3P + 6
falling edge from master, 4-pin mode, polarity = 1, phase = 0
Delay time, slave assertion of SPI_EN active to first SPI_CLK
0.5T + 3P + 6
falling edge from master, 4-pin mode, polarity = 1, phase = 1
(1) T = period of SPI_CLK; P = period of SPI core clock
(2) Figure 7-86 shows only polarity = 0, phase = 0 as an example. In this case, the Master SPI is ready with new data before SPI_EN
assertion.
