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 stabi-
