STANDBY FUNCTION
The standby function is a function to reduce current consumption. The following two kinds of standby functions are
provided.
HALT mode : Halts CPU operating clock and can reduce average current consumption by the intermittent
operation along with the normal operation.
STOP mode : Halts main system clock oscillation. Halts all operations with the main system clock and sets
ultra-low current consumption state with subsystem clock only.
Figure 7-1. Standby Function
Note
Halting the main system clock enables the current consumption to be reduced.
When the CPU is operated by the subsystem clock, the main system clock should be halted by setting the bit
7 (MCC) of the processor clock control register (PCC). The STOP instruction is not available.
Caution
When the main system clock is stopped and the system is operated by the subsystem clock, the
main system clock should be returned to after securing the oscillation stabilization time by a
program.
8.
RESET FUNCTION
There are the following two kinds of resetting methods.
External reset by RESET pin.
Internal reset by watchdog timer runaway time detection.
