Enables/disables the SmaRTClock oscillator and associated bias currents.
0: SmaRTClock oscillator disabled.
1: SmaRTClock oscillator enabled.
Enables/disables the missing SmaRTClock detector.
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.
Should be set to 1 if the system clock is faster than 4x the SmaRTClock frequency.
0: High Speed Mode is disabled.
1: High Speed Mode is enabled.
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.
