MPC8260 PowerQUICC II Integrated Communications Processor Hardware Specifications, Rev. 2
shows signal behavior in MEMC mode.
Generally, all MPC8260 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
