shows signal behavior for all parity modes (including ECC, RMW parity, and standard parity).
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
