456 / 940 page  APPLICATIONS 7733 Group User’s Manual 17–49 17.4.2 Power saving example with wait mode used In this example, power saving is realized by using the wait mode. While power is saved, the clock function is realized by using the clock timer (Timer B2). (1) Specifications The microcomputer operates in the single-chip mode. The frequency of the sub clock (f(XCIN)) = 32.768 kHz. An external clock is used as the sub clock. Clock counting is performed by using the clock timer. (An interrupt request occurs every second.) When an INT0 interrupt request occurs (Note), the wait mode is terminated. Note: An interrupt request occurs at every falling edge of the signal input from pin INT0. In the wait mode, interrupts other than the following interrupts are disabled. •Timer B2 interrupt •INT0 interrupt An external input is used as the main clock. 17.4 Power saving |
