Standby Timer Select 2 to 0
Select the time the MCU waits for the clock to
stabilize when software standby mode is cleared.
Make a selection according to the operating
frequency so that the standby time is at least 8 ms
(oscillation stabilization time). With an external
clock, make a selection according to the operating
frequency so that the standby time is at least 500
μs (output stabilization delay time for external
clock).
For relationship between setting values and the
standby time, see table 22.2.
