Electrical Characteristics
Freescale Semiconductor
22
The UPM machine and GPCM machine outputs change on the internal tick selected by the memory controller configuration.
The AC timing specifications are relative to the internal tick. SDRAM machine outputs change only on the REFCLK rising edge.

Notes:
1.
Timings specifications 13 and 14 in non-pipeline mode are more restrictive than MSC8102 timings.
2.
Values are measured from the 50% TTL transition level relative to the 50% level of the REFCLK rising edge.
3.
Guaranteed by design.
