NOTE

SDR SDRAM CLK parameters are measured from the 50% point—that is,

high is defined as 50% of signal value and low is defined as 50% of signal

value. SD1 + SD2 does not exceed 7.5 ns for 133 MHz.

The timing parameters are similar to the ones used in SDRAM data

sheets—that is, Table 33 indicates SDRAM requirements. All output signals

are driven by the ESDCTL at the negative edge of SDCLK and the

parameters are measured at maximum memory frequency.
