21B.6.3 Setting Oscillation Stabilization Time after Clearing Software Standby Mode
Bits STS2 to STS0 in SBYCR should be set as described below.
Using a Crystal Oscillator: Set bits STS2 to STS0 so that the standby time is at least 8 ms (the
oscillation stabilization time).
Table 21B.5 shows the standby times for different operating frequencies and settings of bits STS2
to STS0.
Table 21B.5 Oscillation Stabilization Time Settings
Note:
Using an External Clock: It is necessary to allow time for the PLL circuit to stabilize. Therefore,
the standby time should be set to a value of 2 ms or greater.

is generated. Software standby mode cannot be cleared if the interrupt has been masked on the
CPU side or has been designated as a DTC activation source.
Clearing with the RES pin
When the RES pin is driven Low, clock oscillation is started. At the same time as clock
oscillation starts, clocks are supplied to the entire chip. Note that the RES pin must be held
Low until clock oscillation stabilizes. When the RES pin goes high, the CPU begins reset
exception handling.
Clearing with the STBY pin
When the STBY pin is driven Low, a transition is made to hardware standby mode.
