Enables/disables the SmaRTClock oscillator and associated bias currents.
0: SmaRTClock oscillator disabled.

0: Missing SmaRTClock detector disabled.
1: Missing SmaRTClock detector enabled.
Set by hardware when a missing SmaRTClock detector timeout occurs. Must be
cleared by software. The value of this bit is not defined when the SmaRTClock
oscillator is disabled.
Controls if the SmaRTClock timer is running or stopped (holds current value).
0: SmaRTClock timer is stopped.
1: SmaRTClock timer is running.
Enables/disables the SmaRTClock alarm function. Also clears the ALRM flag.
0: SmaRTClock alarm disabled.
1: SmaRTClock alarm enabled.
SmaRTClock Alarm Event
Flag and Auto Reset
Enable.
Reads return the state of the
alarm event flag.
Writes enable/disable the
Auto Reset function.
Writing 1 initiates a SmaRTClock timer set operation. This bit is cleared to 0 by hard-
ware to indicate that the timer set operation is complete.
Writing 1 initiates a SmaRTClock timer capture operation. This bit is cleared to 0 by
hardware to indicate that the timer capture operation is complete.
