AC Electrical Characteristics
Figure 12 is a representation of the information in Table 13.
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. The
SDRAM and GPCM machine outputs change on CLKin’s rising edge.
6.3 JTAG Timings
