5.5.2 System Clock Pin Output Function
<Example 1> Transition from STOP mode to NORMAL mode
(Note) The phase difference (AC timing) between the system clock output by the SCOUT
and the internal clock is not guaranteed.
Mode
The system clock, fsys, fsys/2 or fs, can be output from the P46/SCOUT pin. By setting the
port 4 related registers, P4CR<P46C> to "1" and P4FC<P46F> to "1," the P46/SCOUT pin
becomes the SCOUT output pin.
SYSCR3<SCOSEL1:0>.
Table 5.5.2 shows the pin states in each standby mode when the P46/SCOUT pin is set to
the SCOUT output.
SYSCR2<WUPT1:0>=”xx”: Select the warm-up time
SYSCR0<XEN>=”1” :Enable the high speed oscillation (fosc)
SYSCR1<SYSCK>=”0” :Switch the system clock to high speed (fgear)
SYSCR1<SYSCKFLG>Read :”0”(confirm the current system is fgear)
