47.11.3.2 SPI Timings
Notes:
1. 3.3V domain: V
VDDIO
from 2.85V to 3.6V, maximum external capacitor = 40 pF.
2. 1.8V domain: V
VDDIO
from 1.65V to 1.95V, maximum external capacitor = 20 pF.
Note that in SPI master mode, the SAM4E does not sample the data (MISO) on the opposite edge where the data clocks
out (MOSI), but the same edge is used. See
out (MOSI), but the same edge is used. See
