8.4.5
Timing of the Synchronous Dynamic RAM (SDRAM) Interface is simplified as all signals
are referenced to the rising edge of RAMCLK. In
signals output by the ABM-3G have identical delay times with reference to the clock.
When reading from RAM, the ABM-3G samples the data within a window at the rising
clock edge.
