System Bus Access Timing
2.6.5.1 Core Data Transfers
Generally, all MSC8103 bus and system output signals are driven from the rising edge of the reference clock
(REFCLK), which is DLLIN. Memory controller signals, however, trigger on four points within a DLLIN cycle.
Each cycle is divided by four internal ticks: T1, T2, T3, and T4. T1 always occurs at the rising edge of DLLIN (and
T3 at the falling edge), but the spacing of T2 and T4 depends on the PLL clock ratio selected, as Table 2-15 shows.
Figure 2-9 is a graphical representation of Table 2-15.
Note:
The UPM machine and GPCM machine outputs change on the internal tick determined by the memory
controller programming; the AC specifications are relative to the internal tick. SDRAM machine outputs
change only on the DLLIN rising edge.
