■ In every standby mode, the following two operating modes can be selected.
1. Deep standby mode (STBC2:DSTBYX = 0)
In standby mode, the power consumption in deep standby mode is lower than that in normal
standby mode. However, since the device has to wait for the Flash recovery wait time to
elapse before being woken up from deep standby mode by a reset or an interrupt source, it
takes more time to wake up the device from deep standby mode than from normal standby
mode.
2. Normal standby mode (STBC2:DSTBYX = 1)
In standby mode, the power consumption in normal standby mode is higher than that in
deep standby mode. However, since the device does not have to wait for the Flash recovery
wait time to elapse before being woken up from normal standby mode by a reset or an
interrupt source, it takes lesser time to wake up the device from deep standby mode than
from normal standby mode.
For details of the Flash recovery wait time, see Table 3.5-2. For the difference between deep
standby mode and normal standby mode in power consumption, refer to "■ ELECTRICAL
CHARACTERISTICS" in the device data sheet.
