66 the divider control bits can select the operating  
mode, or be used to hold the divider chain reset  
which allows precision setting of the time. When  
the divider chain is changed from reset to the  
operating mode, the first update cycle is one-half  
second later. The divider control bits are also used  
to facilitate testing of the RTC.  
Periodic Interrupt Selection  
The periodic interrupt allows the IRQB port to be  
triggered from once every 500 ms to once every  
122.07 μs. As Table 67 shows, the periodic  
interrupt is selected with the RS0-RS3 bits in  
Register A. The periodic interrupt is enabled with  
the PIE bit in Register B.
