NOTE
Generally, all SoC bus and system output signals are driven from the rising
edge of the input clock (CLKin). Memory controller signals, however,
trigger on four points within a CLKin cycle. Each cycle is divided by four
internal ticks: T1, T2, T3, and T4. T1 always occurs at the rising edge, and
T3 at the falling edge, of CLKin. However, the spacing of T2 and T4
depends on the PLL clock ratio selected, as shown in Table 15.
