Notes: 1. For t_RDAC2, use t_cyc × (n + 1.65) – 35 (for 35% duty) or t_cyc × (n + 1.5) – 35 (for 50% duty)
instead of t_cyc × (n + 2) – t_RDD – t_RDS.
2. For t_ACC2, use t_cyc × (n + 2) – 44 instead of t_cyc × (n + 2) – t_AD (or t_CSD1) – t_RDS.
3. t_RDH is measured from A21-A0, CSn, or RD, whichever is negated first.
