DS1306
6 of 17
AIE1 (Alarm Interrupt Enable 1) - When set to a logic 1, this bit permits the Interrupt 1 Request Flag
(IRQF1) bit in the status register to assert INT1. When the AIE1 bit is set to logic 0, the IRQF1 bit does
not initiate an interrupt signal, and the INT1 pin is set to a logic 0 state.

IRQF0 (Interrupt 0 Request Flag) - A logic 1 in the Interrupt Request Flag bit indicates that the current
time has matched the Alarm 0 registers. If the AIE0 bit is also a logic 1, the INT0 pin will go low.
IRQF0 is cleared when any of the Alarm 0 registers are read or written.
IRQF1 (Interrupt 1 Request Flag) - A logic 1 in the Interrupt Request Flag bit indicates that the current
time has matched the Alarm 1 registers. If the AIE1 bit is also a logic 1, the INT1 pin will generate a
62.5- ms active high pulse. IRQF1 is cleared when any of the Alarm 1 registers are read or written.
TRICKLE CHARGE REGISTER (READ 11H, WRITE 91H)
This register controls the trickle charge characteristics of the DS1306. The simplified schematic of
Figure 3 shows the basic components of the trickle charger. The trickle charge select (TCS) bits (bits
4-7) control the selection of the trickle charger. In order to prevent accidental enabling, only a pattern of
1010 will enable the trickle charger. All other patterns will disable the trickle charger. The DS1306
powers up with the trickle charger disabled. The diode select (DS) bits (bits 2-3) select whether one
diode or two diodes are connected between VCC1 and VCC2. If DS is 01, one diode is selected. If DS is
10, two diodes are selected. If DS is 00 or 11, the trickle charger is disabled independently of TCS. The
RS bits select the resistor that is connected between VCC1 and VCC2. The resistor is selected by the
resistor select (RS) bits as shown in Table 2.
