DS1306
5 of 17
The DS1306 can be run in either 12-hour or 24-hour mode. Bit 6 of the hours register is defined as the
12- or 24-hour mode select bit. When high, the 12-hour mode is selected. In the 12-hour mode, bit 5 is
the AM/PM bit with logic high being PM.
In the 24-hour mode, bit 5 is the second 10-hour bit
(20-23 hours).
The DS1306 contains two time of day alarms. Time of Day Alarm 0 can be set by writing to registers
87h to 8Ah. Time of Day Alarm 1 can be set by writing to registers 8 Bh to 8 Eh. Bit 7 of each of the
time of day alarm registers are mask bits (Table 1). When all of the mask bits are logic 0, a time of day
alarm will only occur once per week when the values stored in timekeeping registers 00h to 03h match
the values stored in the time of day alarm registers. An alarm will be generated every day when bit 7 of
the day alarm register is set to a logic 1. An alarm will be generated every hour when bit 7 of the day and
hour alarm registers is set to a logic 1. Similarly, an alarm will be 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 will occur every second.

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.
1 Hz (1 Hz output enable) - This bit controls the 1 Hz output. When this bit is a logic 1, the 1 Hz output
is enabled. When this bit is a logic 0, the 1 Hz 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.
