The time required for restoration from the IDLE2 and STOP modes is as follows.
(a) When transitioning to the IDLE2 or STOP mode from the clock through mode
(b) When transitioning to the IDLE 2 or STOP mode while remaining in the PLL operation mode
• STOP mode: Set the OSTS register so that the oscillation stabilization time is at least 1 ms.
• IDLE2 mode: Set the OSTS register so that the setup time is at least 350
• STOP mode: Set the OSTS register so that the oscillation stabilization time is at least 1 ms.
• IDLE2 mode: Set the OSTS register so that the setup time is at least 350
• STOP mode: Set the OSTS register so that the oscillation stabilization time is at least 1 ms.
• IDLE2 mode: Set the OSTS register so that the setup time is at least 800
