Description
Software Standby
Selects the mode to transit after the execution of the
SLEEP instruction.
0: A transition is made to sleep mode or subsleep
1: A transition is made to standby mode or watch mode.
For details, see table 5.2.
Standby Timer Select 2 to 0
Designate the time the CPU and peripheral modules
wait for stable clock operation after exiting from standby
mode, subactive mode, or watch mode to active mode
or sleep mode due to an interrupt. The designation
should be made according to the operating frequency
so that the waiting time is at least equal to the
oscillation stabilization time. The relationship between
the specified value and the number of wait states is
shown in table 5.1.
When an external clock is to be used, the minimum
value (STS2 = 1, STS1 = 1, and STS0 = 1) is
recommended. When the on-chip oscillator is to be
used, the minimum value (STS2 = 1, STS1 = 1, and
STS0 = 1) is recommended. If a setting other than the
recommended value is made, operation may start
before the end of the waiting time.
