15.8. smaRTClock (Real Time Clock) Reset
The smaRTClock can generate a system reset on two events: smaRTClock Oscillator Fail or smaRTClock
Alarm. The smaRTClock Oscillator Fail event occurs when the smaRTClock Missing Clock Detector is
enabled and the smaRTClock clock is below approximately 20 kHz. A smaRTClock alarm event occurs
when the smaRTClock Alarm is enabled and the smaRTClock timer value matches the ALARMn registers.
The smaRTClock can be configured as a reset source by writing a ‘1’ to the RTC0RE flag (RSTSRC.7).
The state of the RST pin is unaffected by this reset.
15.9. Software Reset
Software may force a reset by writing a ‘1’ to the SWRSF bit (RSTSRC.4). The SWRSF bit will read ‘1’ fol-
lowing a software forced reset. The state of the RST pin is unaffected by this reset.
