XAF
(1) XAF (Extended Alarm Interrupt Flag: Read only)
The Extended Alarm interrupt Flag (XAF) is set when the current time matches the extended alarm register time. If the
XAIE bit is also set to logic one, the XIRQ pin is driven low. The XAF bit is cleared by a read of register C.
(2) Bits 7 through 1 (Read only)
The remaining bits in Extended alarm register 7 are read only and will always read as 0.
gOPERATION PROCEDURE
1. Initial Settings During Power On (RTC pin = "L")
(1) Settings During Initial Power On (For RTC-6581/6583/6587 only.)
Chip enable delay by interval function of IC.
Oscillator on.
Allows oscillation to stabilize.
(1) Settings During Initial Power On (For RTC-6591/6593/6597 only.)
(Disbale XIRQ)
*1 Since the XIRQ signal is indeterminate at initial power on,
disable is necessary.
