5.4.4. Effect of Watch Mode
The effect of watch mode is described below.
You can reduce power consumption on the external input event wait state drastically by using watch mode.
This mode does not decrease power consumption as much as that of in stop mode because enabled clock
oscillation will continue to run. On the other hand, a clock timer can continue to run and a return to the
program operation is possible by generating a wake up request in a short time compared with the return
from the stop mode.*
* : When continue to run program with activate clocks.
