7) FSEL0, 1 (FOUT frequency Select 0, 1) bits
The combination of these two bits is used to set the FOUT frequency.
Note: All frequencies are temperature compensated!

8) CSEL0, 1 (Compensation interval Select 0, 1) bits
The combination of these two bits is used to set the temperature compensation interval.
Please refer to 8.9. Temperature Compensation Function
9) AF (Alarm Flag) bit
If set to "0" beforehand, this flag bit's value changes from "0" to "1" when an alarm interrupt event has occurred.
Once this flag bit's value is "1", its value is retained until a "0" is written to it.
Please refer to 8.5. Alarm Interrupt Function.
10) TF (Timer Flag) bit
If set to "0" beforehand, this flag bit's value changes from "0" to "1" when a wakeup timer interrupt event has
occurred. Once this flag bit's value is "1", its value is retained until a "0" is written to it.
Please refer to 8.6. Wakeup Timer Interrupt Function.
11) UF (Update Flag) bit
If set to "0" beforehand, this flag bit's value changes from "0" to "1" when a time update interrupt event has
occurred. Once this flag bit's value is "1", its value is retained until a "0" is written to it.
Please refer to 8.7. Time Update Interrupt Function.
12) AIE, TIE, UIE (Alarm, Wakeup Timer, Update Interrupt Enable) bit
In case of Alarm or Wakeup Timer or Update occurs AIE, TIE, UIE bit controls /INT output.
When a "1" is written to this bit, an interrupt signal is generated (/INT status changes from Hi-Z to low) .
When a "0" is written to this bit, no interrupt signal is generated.
Please refer to each function.

1A SOUT set0
1) SOUT set1 register (19h)
By setting 69h =01101001b into SOUT set1 SOUT function becomes activated.
Other data than 69h makes SOUT function non active. Then SOUT becomes Hi-Z.
2) DCE bit ((Direct Control Enable), DC bit (Direct Control)
In case of DCE=1, DC bit Value is outputted at SOUT.
In case of DCE=0, register value Flag value is outputted at SOUT.
