11. STANDBY FUNCTION
This function is to reduce the power dissipation of the chip, and can be used in the following modes:
HALT mode
: Stops supply of the operating clock to the CPU. This mode is used in combination
with the normal operation mode for intermittent operation to reduce the average
power dissipation.
: Stops the entire system with the oscillation circuit continuing operation. The
power dissipation in this mode is close to that in the STOP mode. However, the
time required to restore the normal program operation from this mode is almost
the same as that from the HALT mode.
: Stops the main system clock and thereby to stop all the internal operations of the
chip. Consequently, the power dissipation is minimized with only leakage current
flowing.
: The main system clock is stopped with the subsystem clock used as the system
clock. The CPU can operate on the subsystem clock to reduce the current
consumption.
Power-saving HALT mode: This is a standby function in the power-saving mode and stops the operation clock
of the CPU, to reduce the power dissipation of the entire system.
Power-saving IDLE mode : This is a standby function in the power-saving mode and stops the entire system
except the oscillation circuit, to reduce the power dissipation of the entire system.
IDLE mode
STOP mode
Power-saving mode
These modes are programmable.
In addition, the macro service can be started in the HALT mode or power-saving HALT mode. The HALT mode
is restored again after execution of the macro service processing.
