Bit 7: Oscillator Stop Flag (OSF). A logic 1 in this bit indicates that the oscillator either is stopped or was stopped  
for some period of time and may be used to judge the validity of the clock and calendar data. This bit is set to logic  
1 anytime the oscillator stops. The following are examples of conditions that can cause the OSF bit to be set:  
1) The first time power is applied.  
2) The voltage present on VCC is insufficient to support oscillation.  
3) The EOSC bit is turned off.  
4) External influences on the crystal (e.g., noise, leakage, etc.).  
This bit remains at logic 1 until written to logic 0. This bit can only be written to a logic 0.  
Bit 1: Alarm 2 Flag (A2F). A logic 1 in the alarm 2 flag bit indicates that the time matched the alarm 2 registers.  
This flag can be used to generate an interrupt on either INTA or SQW/INTB depending on the status of the INTCN  
bit in the control register. If the INTCN bit is set to logic 0 and A2F is at logic 1 (and A2IE bit is also logic 1), the INTA  
pin goes low. If the INTCN bit is set to logic 1 and A2F is logic 1 (and A2IE bit is also logic 1), the SQW/INTB pin  
goes low. A2F is cleared when written to logic 0. This bit can only be written to logic 0. Attempting to write to logic 1  
leaves the value unchanged.  
Bit 0: Alarm 1 Flag (A1F). A logic 1 in the Alarm 1 Flag bit indicates that the time matched the alarm 1 registers. If  
the A1IE bit is also a logic 1, the INTA pin goes low. A1F is cleared when written to logic 0. This bit can only be  
written to logic 0. Attempting to write to logic 1 leaves the value unchanged.
