Bits 6 to 4—Standby Timer Select 2 to 0 (STS2 to STS0): These bits select the length of time
the CPU and on-chip supporting modules wait for the internal clock oscillator to settle when
software standby mode is exited by an external interrupt.
When using a crystal oscillator, set these bits so that the waiting time will be at least 7 ms at the
system clock rate.
For further information about waiting time selection, see section 20.4.3, Selection of Waiting
Time for Exit from Software Standby Mode.
