NOTE
Generally, all MPC8280 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 13.
