MICROCONTROLLER AND METHOD OF CONTROLLING THE SAME |
| 摘要 |
A microcontroller includes a CPU (Central Processing Unit), a data input unit, and an oscillator that supplies a clock signal in response to operational modes of the microcontroller. The operational modes include a STOP mode, a SNOOZE mode and a RUN mode, in the STOP mode, the oscillator and the CPU are stopped, in the RUN mode, the CPU and the data input unit operate using the clock signal supplied from the oscillator, and in the SNOOZE mode, the oscillator starts and supplies the clock signal to the data input unit when the data input unit receives first data, and the microcontroller switches to the RUN mode after the data input unit receives second data using the clock signal. |
