The BMU timing specifications are shown in
The BMU synchronous DRAM interface is PC100-compliant and designed to work with
industry standard SDRAM components with 12 or fewer address lines. The information
below is intended to provide the output, setup, and hold data required to design this
interface without duplicating the transaction waveform diagrams in SDRAM data sheets.
