Preliminary
10.9 Reset, Stop, Wait, Mode Select, and Interrupt Timing
3. Substitute BMDAR for MDAR if there is no chip select
4. MDAR is active in this calculation only when the chip select changes.
Table 10-17 Reset, Stop, Wait, Mode Select, and Interrupt Timing1,2
1. In the formulas, T = clock cycle. For an operating frequency of 60MHz, T = 16.67ns. At 8MHz (used during Reset and Stop
modes), T = 125ns.
2. Parameters listed are guaranteed by design.

4. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This is
not the minimum required so that the IRQA interrupt is accepted.
