CLKSEL=DIVIDED_IRC_CLOCK_T, ALARMFLAG=NO_TIME_OUT_THE_SEL, CLEARCTR=NO_EFFECT_READING_T
Self wake-up timer control register.
| CLKSEL | Select the self wake-up timer clock source. 0 (DIVIDED_IRC_CLOCK_T): Divided IRC clock. This clock runs at 750 kHz and provides time-out periods of up to approximately 95 minutes in 1.33 us increments. This clock is not available in most low-power modes and must not be selected if the timer is to be used to wake up from one of these modes. 1 (LOW_POWER_CLOCK_THI): Low power clock. This is the (nominally) 10 kHz clock and provides time-out periods of up to approximately 119 hours in 100 CTS can be from the input pin, or fs increments. The accuracy of this clock is limited to +/- 45 % over temperature and processing. This clock is available in all power modes. Prior to use, the low-power oscillator must be enabled. The oscillator must also be set to remain active in Deep power-down if needed. |
| ALARMFLAG | Wake-up or alarm timer flag. 0 (NO_TIME_OUT_THE_SEL): No time-out. The self wake-up timer has not timed out. Writing a 0 to has no effect. 1 (TIME_OUT_THE_SELF_W): Time-out. The self wake-up timer has timed out. This flag generates an interrupt request which can wake up the part from any low power mode not deep power-down. Writing a 1 clears this status bit and the interrupt too? |
| CLEARCTR | Clears the self wake-up timer. 0 (NO_EFFECT_READING_T): No effect. Reading this bit always returns 0. 1 (CLEAR_THE_COUNTER_C): Clear the counter. Counting is halted until a new count value is loaded. |
