(4) SLOW mode
a.
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 (TC2).
low-frequency clock for SLOW2 mode.
stabilizes before performing the above operations. The timer/counter 2 (TC2) can
conveniently be used to confirm that low-frequency clock oscillation has
stabilized.
Switching from NORMAL2 mode to SLOW1 mode
Note: The high-frequency clock oscillation can be continued to return quickly to
Example 1: Switching from NORMAL2 mode to SLOW1 mode.
Example2: Switching to the SLOW1 mode after low-frequency clock has stabilized.
PINTTC2:
VINTTC2:
First, set SYSCR2<SYSCK> to switch the main system clock to the
Next, clear SYSCR2<XEN> to turn off high-frequency oscillation.
When the low-frequency clock oscillation is unstable, wait until oscillation
NORMAL2 mode. But starting STOP mode while SLOW mode, the
high-frequency oscillation must be stopped.
