Description
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
interrupt or when a transition is made from subclock
operation to main clock operation. With a crystal
resonator, refer to table 28.2 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 28.2 to set the standby time.
While oscillation is being settled, the timer is counted on
the Pφ clock frequency. Careful consideration is required
in multi-clock mode.
