Figure 38. Mobile DDR SDRAM DQ versus DQS and SDCLK Read Cycle Timing Diagram
NOTE
SDRAM CLK and DQS related parameters are being measured from the
50% point—that is, high is defined as 50% of signal value and low is
defined as 50% of signal value.
The timing parameters are similar to the ones used in SDRAM data
sheets—that is, Table 38 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.

ETM Electrical Specifications
ETM is an ARM protocol. The timing specifications in this section are given as a guide for a TPA that
supports TRACECLK frequencies up to 133 MHz.
Figure 39 depicts the TRACECLK timings of ETM, and Table 39 lists the timing parameters.
