Notes: *1 For tRDAC2, use tcyc à (n + 1.65) â 35 (for 35% duty) or tcyc à (n + 1.5) â 35 (for
50% duty) instead of tcyc à (n + 2) â tRDD â tRDS.
*2 For tACC2, use tcyc à (n + 2) â 44 instead of tcyc à (n + 2) â tAD (or tCSD1) â tRDS480.
*3 tRDH is measured from A21âA0, CSn, or RD, whichever is negated first.
