7. STANDBY FUNCTION
7.1
Standby Function
The standby function is supported to minimize the system’s power consumption. There are two standby modes:
HALT and STOP.
HALT and STOP modes are selected using the HALT and STOP instructions, respectively.
(1) HALT mode
In HALT mode, the CPU clock is stopped. Interleaving normal mode with HALT mode can reduce the average
power consumption.
(2) STOP mode
In STOP mode, the main system clock is stopped. As a result, main system clock-based operation is also
stopped, thus minimizing power consumption.
Caution
Before shifting to STOP mode, first stop the operation of the hardware, then execute the
STOP instruction.
