10. STANDBY FUNCTION
This function is to reduce the power consumption 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 consumption.
Stops the entire system except for the oscillator, which continues
operating. The power consumption 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 stops all the internal
operations of the chip. Consequently, the power consumption is
minimized with only leakage current flowing.
The main system clock is stopped and the subsystem clock is used as
the system clock. The CPU can operate on the subsystem clock to
reduce the current consumption.
IDLE mode:
STOP mode:
Low power consumption mode:
Low power consumption HALT mode: This is a standby function in the low power consumption mode and
stops the operation clock of the CPU, to reduce the power consumption
of the entire system.
Low power consumption IDLE mode:
This is a standby function in the low power consumption mode and
stops the entire system except the oscillator, to reduce the power
consumption of the entire system.
These modes are programmable.
The macro service can be started from the HALT mode or low power consumption HALT mode. After macro
service processing is executed, the system returns to the HALT mode again.
The transition of the standby status is shown in Figure 10-1.
