Figure 9 MCU Status Transitions
Active Mode:
The MCU operates according to the clock generated by the system oscillators OSC
1
and
OSC
2
.
Standby Mode:
The MCU enters standby mode when the SBY instruction is executed from active mode.
In this mode, the oscillators, interrupts, timer/counters, and serial interface continue to operate, but all
instruction execution-related clocks stop. The stopping of these clocks stops the CPU, retaining all RAM
and register contents and maintaining the current I/O pin status.
Standby mode is terminated by a RESET input oran interrupt request. If it is terminated by a RESET input,
the MCU is reset as well. After an interrupt request, the MCU enters active mode and resumes, executing
