Note: RS3–RS0 determine periodic interrupt rates as listed for E32K = 0.
The third method uses a periodic interrupt to determine if an update cycle is in progress. The UIP bit in
Register A is set high between the setting of the PF bit in Register C (see Figure 3). Periodic interrupts
that occur at a rate of greater than tBUC allow valid time and date information to be reached at each
occurrence of the periodic interrupt. The reads should be complete within (tPI / 2 + tBUC) to ensure that
data is not read during the update cycle.
