P = SYSCLK2 period; M = tc(SPC)M (SPI master 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. MO(0) refers to first bit and MO(n) refers to last bit output on
SPI1_SIMO. MI(0) refers to the first bit input and MI(n) refers to the last bit input on SPI1_SOMI.
