²P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.

³ SDCAS/SSADS, SDRAS/SSOE, and SDWE/SSWE operate as SDCAS, SDRAS, and SDWE, respectively, during SDRAM accesses.

§For the first write in a series of one or more consecutive adjacent writes, the write data is generated one CLKOUT2 cycle early to accommodate the ED enable time.
