Note:
Initial Power-on defaults
Upon application of power to the device, the register bits in the RTC will initially power-on in
the state indicated in Table below.
Table 7.
All other control bits power-up in an undetermined state. The user should write the OF bit to
a 0 after 4s (after the oscillator has started up and the clock is stable). If the OFIE is to be
enabled, then write a ‘1’ to the OFIE bit in the RTC register.
