Section 11 Realtime Clock (RTC)
Bit 7—Carry Flag (CF): This flag is set to 1 on generation of a second counter carry, or a 64 Hz
counter carry when the 64 Hz counter is read. The count register value read at this time is not
guaranteed, and so the count register must be read again.

Bit 4—Carry Interrupt Enable Flag (CIE): Enables or disables interrupt generation when the
carry flag (CF) is set to 1.
