7. STANDBY FUNCTIONS
There are the following two standby functions to reduce the current consumption.
HALT mode : The CPU operating clock is stopped. The average current consumption can be reduced by
intermittent operation in combination with the normal operating mode.
STOP mode : The main system clock oscillation is stopped. The whole operation by the main system clock
is stopped, so that the system operates with ultra-low power dissipation.

8. RESET FUNCTIONS
There are the following two reset methods.
External reset input by RESET pin.
Internal reset by watchdog timer runaway time detection.
