Notes: 1. RESETP, NMI, and IRQ5 to IRQ0 are asynchronous. Changes are detected at the
clock fall when the setup shown is used. When the setup cannot be used, detection
can be delayed until the next clock falls.
2. In the standby mode, tRESPW = tOSC1 (100 µs) when XTAL oscillation is continued and
tRESPW = tOSC2 (10 ms) when XTAL oscillation is off. In the sleep mode, tRESPW = tPLL1
(100 µs).
When the clock multiplication ratio is changed, tRESPW = tPLL1 (100 µs).
3. In the standby mode, tRESMW = tOSC2 (10 ms). In the sleep mode, RESETM must be kept
low until STATUS (0-1) changes to reset (HH). When the clock multiplication ratio is
changed, RESETM must be kept low until STATUS (0-1) changes to reset (HH).
