Description
Software Standby
This bit 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.
For details, see table 6.2.
Standby Timer Select 2 to 0
These bits designate the time the CPU and peripheral
modules wait for stable clock operation after exiting
from standby mode, subactive mode, or subsleep mode
to active mode or sleep mode due to an interrupt. The
designation should be made according to the clock
frequency so that the waiting time is at least 6.5 ms.
The relationship between the specified value and the
number of wait states is shown in table 6.1. When an
external clock is to be used, the minimum value (STS2
= STS1 = STS0 = 1) is recommended.
mode.
