Standby Timer Select 4 to 0
These bits select the time the MCU waits for the clock to
settle when software standby mode is cleared by an
external interrupt. With a crystal resonator, refer to table
18.2 and make a selection according to the operating
frequency so that the standby time is at least equal to the
oscillation settling time. With an external clock, a PLL
circuit settling time is necessary. Refer to table 18.2 to set
the standby time.
While oscillation is being settled, the timer is counted on
the P
φ
clock frequency. Careful consideration is required
in multi-clock mode.
