Notes: 1. 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 time is the time between the TK edge and the signal stabilization. Figure
45-20 illustrates Min and Max accesses for SSC
