RX210 Group 5. Electrical Characteristics
5.3.3 Timing of Recovery from Low Power Consumption Modes
[Chip versions A and C]
Note 1. The recovery time varies depending on the state of each oscillator when the WAIT instruction is executed. The recovery time
when multiple oscillators are operating varies depending on the operating state of the oscillators that are not selected as the
system clock source, and depends on the time set in the wait control registers corresponding to the oscillators.
Note 2. The indicated value is measured for an 8 MHz crystal resonator.
Note 3. When RCR3.RTCEN = 1, the time will be the time set in the SOSCWTCR register minus 2 s.
Note 4. When RCR3.RTCEN = 1, the time will be the time set in the SOSCWTCR register minus 2 s and plus 31.25 ms.
