Note:
1. Time from wakeup request until first instruction is executed. Wakeup results in device reset.
2. VSCALE0 to VSCALE2 voltage change transitions occur at a rate of 10 mV/μs for approximately 20 μs. During this transition,
peak currents will be dependent on the value of the DECOUPLE output capacitor, from 35 mA (with a 1 μF capacitor) to 70 mA
(with a 2.7 μF capacitor).
3. Scaling down from VSCALE2 to VSCALE0 requires approximately 2.8 μs + 29 HFCLKs.
4. Scaling up from VSCALE0 to VSCALE2 requires approximately 30.3 μs + 28 HFCLKs.
