SLOW mode
SLOW mode is controlled by the system control register 2 (SYSCR2).
The following is the methods to switch the mode with the warm-up counter.
(1)
Switching from NORMAL2 mode to SLOW1 mode
First, set SYSCR2<SYSCK> to switch the main system clock to the low-frequency clock for
SLOW2 mode. Next, clear SYSCR2<XEN> to turn off high-frequency oscillation.
Note: The high-frequency clock can be continued oscillation in order to return to NORMAL2 mode from
SLOW mode quickly. Always turn off oscillation of high-frequency clock when switching from
SLOW mode to stop mode.
Example 1 :Switching from NORMAL2 mode to SLOW1 mode.
