Timing of Recovery from Low Power Consumption Modes
Table 5.20 Timing of Recovery from Low Power Consumption Modes
Conditions 1: VCC = AVCC0 = VREFH0 = 2.7 to 3.6 V, VREFH = 2.7 V to AVCC0, VSS = AVSS0 = VREFL = VREFL0 = 0 V,
T_a = –40 to +85°C
Conditions 2: VCC = AVCC0 = VREFH0 = 4.0 to 5.5 V, VREFH = 4.0 V to AVCC0, VSS = AVSS0 = VREFL = VREFL0 = 0 V,
T_a = –40 to +85°C

Note:
The wait time varies depending on the state in which each oscillator was when the WAIT instruction was executed. The recovery
time when multiple oscillators are operating is the same period as that when the oscillator which requires the longest time of all
operating oscillators to recover is operating alone.
