DS1306
7 of 22
registers is set to a logic 1. Similarly, an alarm is generated every minute when bit 7 of the day, hour, and
minute alarm registers is set to a logic 1. When bit 7 of the day, hour, minute, and seconds alarm registers
is set to a logic 1, an alarm occurs every second.
During each clock update, the RTC compares the Alarm 0 and Alarm 1 registers with the corresponding
clock registers. When a match occurs, the corresponding alarm flag bit in the status register is set to a 1. If
the corresponding alarm interrupt enable bit is enabled, an interrupt output is activated.

SPECIAL PURPOSE REGISTERS
The DS1306 has three additional registers (control register, status register, and trickle charger register)
that control the real-time clock, interrupts, and trickle charger.

WP (Write Protect) – Before any write operation to the clock or RAM, this bit must be logic 0. When
high, the write protect bit prevents a write operation to any register, including bits 0, 1, and 2 of the
control register. Upon initial power-up, the state of the WP bit is undefined. Therefore, the WP bit should
be cleared before attempting to write to the device. When WP is set, it must be cleared before any other
control register bit can be written.
1Hz (1Hz Output Enable) – This bit controls the 1Hz output. When this bit is a logic 1, the 1Hz output
is enabled. When this bit is a logic 0, the 1Hz output is high-Z.
AIE0 (Alarm Interrupt Enable 0) – When set to a logic 1, this bit permits the interrupt 0 request flag
(IRQF0) bit in the status register to assert INT0 . When the AIE0 bit is set to logic 0, the IRQF0 bit does
not initiate the INT0 signal.
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.
