23.1 Overview
selecting the appropriate mode for the application. The available standby modes are listed in Table 23-1.
Notes1.
HALT mode
IDLE1 mode
IDLE2 mode
STOP mode
Subclock operation mode
Sub-IDLE mode
RTC backup mode
The power consumption of the system can be effectively reduced by using the standby modes in combination and
2.
In the IDLE1 or sub-IDLE mode, the PLL retains the operating status immediately before mode transition. If
the PLL operation is not necessary, stop the PLL to lower the power consumption. In the IDLE2 mode,
mode transition causes the PLL to stop automatically.

Mode in which the RTC continues counting on the subclock based the supply of backup voltage to
the RV
separated from other internal circuits. The power consumption in this mode is even lower than in low-
voltage STOP mode.
Mode in which only the operating clock of the CPU is stopped.
The total current consumption of the system can be reduced by using this mode in combination
with the normal operation mode for intermittent operation.
Mode in which all the operations of the internal circuits except the oscillator, PLL
memory are stopped.
This mode can reduce the power consumption to a level lower than the HALT mode because it
stops the operation of the on-chip peripheral functions.
Mode in which all the operations of the internal circuits except the oscillator are stopped.
This mode can reduce the power consumption to a level lower than the IDLE1 mode because it
stops the operations of the on-chip peripheral functions, PLL, and flash memory.
Mode in which all the operations of the internal circuits except the subclock oscillator are stopped.
This mode can reduce the power consumption to a level lower than the IDLE2 mode.
Two modes are available: STOP mode and low-voltage STOP mode.
The power consumption decreases further in the low-voltage STOP mode because the voltage of
the regulator is lowered.
Mode in which the subclock is used as the internal system clock.
This mode can reduce the power consumption to a level lower than the normal operation mode.
Two modes are available: subclock operation mode and low-voltage subclock operation mode.
The power consumption decreases further in the low-voltage subclock operation mode because
the voltage of the regulator is lowered.
Mode in which all the operations of the internal circuits except the oscillator, PLL operation
flash memory are stopped, in the subclock operation mode.
This mode can reduce the power consumption to a level lower than the subclock operation mode.
Two modes are available: sub-IDLE mode and low-voltage sub-IDLE mode.
The power consumption decreases further in the low-voltage sub-IDLE mode because the voltage
of the regulator is lowered.
Note that the data of the internal RAM and the values of the CPU registers cannot be held in RTC
backup mode, so when restoring the system from this mode, be sure to stop reset signal input after
resupplying V
