| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 7 | RTCOFIE | RW | 0h |
32-kHz crystal oscillator fault interrupt enable. This interrupt can be used as LPM3.5 wake-up event. 0b = Interrupt not enabled 1b = Interrupt enabled (LPM3.5 wake-up enabled) |
| 6 | RTCTEVIE | RW | 0h |
Real-time clock time event interrupt enable. In modules supporting LPM3.5 this interrupt can be used as LPM3.5 wake-up event. 0b = Interrupt not enabled 1b = Interrupt enabled (LPM3.5 wake-up enabled) |
| 5 | RTCAIE | RW | 0h |
Real-time clock alarm interrupt enable. In modules supporting LPM3.5 this interrupt can be used as LPM3.5 wake-up event. 0b = Interrupt not enabled 1b = Interrupt enabled (LPM3.5 wake-up enabled) |
| 4 | RTCRDYIE | RW | 0h |
Real-time clock ready interrupt enable 0b = Interrupt not enabled 1b = Interrupt enabled |
| 3 | RTCOFIFG | RW | 0h |
32-kHz crystal oscillator fault interrupt flag. This interrupt can be used as LPM3.5 wake-up event. It also indicates a clock failure during backup operation. 0b = No interrupt pending 1b = Interrupt pending. A 32-kHz crystal oscillator fault occurred after last reset. |
| 2 | RTCTEVIFG | RW | 0h |
Real-time clock time event interrupt flag. In modules supporting LPM3.5 this interrupt can be used as LPM3.5 wake-up event. 0b = No time event occurred 1b = Time event occurred |
| 1 | RTCAIFG | RW | 0h |
Real-time clock alarm interrupt flag. In modules supporting LPM3.5 this interrupt can be used as LPM3.5 wake-up event. 0b = No time event occurred 1b = Time event occurred |
| 0 | RTCRDYIFG | RW | 0h |
Real-time clock ready interrupt flag 0b = RTC cannot be read safely 1b = RTC can be read safely |
