SAM4S Series [Preliminary]
42.11.5.1 SSC Timings
Notes: 1. Timings SSC4 and SSC7 depend on the start condition. When STTDLY = 0 (Receive start delay) and START = 4, or 5 or
7(Receive Start Selection), two Periods of the MCK must be added to timings.
2. For output signals (TF, TD, RF), Min and Max access times are defined. The Min access time is the time between the TK (or
RK) edge and the signal change. The Max access timing is the time between the TK edge and the signal stabilization. Figure
42-23 illustrates Min and Max accesses for SSC0. The same applies for SSC1, SSC4, and SSC7, SSC10 and SSC13.
3. 1.8V domain: V
VDDIO
from 1.65V to 1.95V, maximum external capacitor = 20 pF.
4. 3.3V domain: V
VDDIO
from 2.85V to 3.6V, maximum external capacitor = 30 pF..
