AC Electrical Characteristics
This table is a representation of the information in Table 15.
Figure 12. Internal Tick Spacing for Memory Controller Signals
NOTE
The UPM machine outputs change on the internal tick determined by the
memory controller programming; the AC specifications are relative to the
internal tick. Note that SDRAM and GPCM machine outputs change on
CLKin’s rising edge.
