(1) P = SYSCLK2 period; S = tc(SPC)S (SPI slave bit clock period)
(2) This timing is limited by the timing shown or 3P, whichever is greater.
(3) First bit may be MSB or LSB depending upon SPI configuration. SO(0) refers to first bit and SO(n) refers to last bit output on SPI1_SOMI. SI(0) refers to the first bit input and SI(n) refers to the last bit input on SPI1_SIMO.
(4) Measured from the termination of the write of new data to the SPI module, In analyzing throughput requirements, additional internal bus cycles must be accounted for to allow data to be written to the SPI module by the CPU.
