SmaRTClock Interface Busy Indicator.
Indicates SmaRTClock interface status. Writing 1 to this bit initiates an indirect read.
Enables/disables Autoread.
0: Autoread Disabled.
1: Autoread Enabled.
Read = 0b; Write = Don’t Care.
Short Strobe Enable.
Enables/disables the Short Strobe Feature. It is recommended to always enable the short
strobe feature to minimize the read/write time.
0: Short Strobe disabled.
1: Short Strobe enabled.
Sets the currently selected SmaRTClock register.
See Table 11.1 for a listing of all SmaRTClock indirect registers.
Holds data transferred to/from the internal SmaRTClock register selected by RTCADR.
