| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 7 | Reserved | R | 0h |
Reserved. Always reads as 0. |
| 6 | OUT | RW | 0h |
RTCCAPx output 0b = Output low 1b = Output high |
| 5 | DIR | RW | 0h |
RTCCAPx pin direction 0b = RTCCAPx pin configured as input 1b = RTCCAPx pin configured as output |
| 4 | IN | R | 0h |
RTCCAPx input. The external input on RTCCAPx pin can be read by this bit. 0b = Input is low 1b = Input is high |
| 3 | REN | RW | 0h |
RTCCAPx pin pullup or pulldown resistor enable. When respective pin is configured as input, setting this bit enables the pullup or pulldown (see Table 29-1). 0b = Pullup or pulldown disabled 1b = Pullup or pulldown enabled |
| 2 | CAPES | RW | 0h |
Event edge selection 0b = Event on a low-to-high transition 1b = Event on a high-to-low transition |
| 1 | Reserved | R | 0h |
Reserved. Always reads as 0. |
| 0 | CAPEV | RW | 0h |
Tamper event status flag. All subsequent events on RTCCAPx after CAPEV is set are ignored until CAPEV is cleared by the user. Can only be written as 0. 0b = Tamper event did not occur 1b = Tamper event occurred |
