SPECIAL-PURPOSE REGISTERS
The DS1337 has two additional registers (control and status) that control the RTC, alarms, and square-wave
output.

Bit 7: Enable Oscillator (EOSC). This active-low bit when set to logic 0 starts the oscillator. When this bit is set to
logic 1, the oscillator is stopped. This bit is enabled (logic 0) when power is first applied.
Bits 4 and 3: Rate Select (RS2 and RS1). These bits control the frequency of the square-wave output when the
square wave has been enabled. The table below shows the square-wave frequencies that can be selected with the
RS bits. These bits are both set to logic 1 (32kHz) when power is first applied.

Bit 2: Interrupt Control (INTCN). This bit controls the relationship between the two alarms and the interrupt output
pins. When the INTCN bit is set to logic 1, a match between the timekeeping registers and the alarm 1 registers l
activates the
INTA pin (provided that the alarm is enabled) and a match between the timekeeping registers and the
alarm 2 registers activates the SQW/
INTB pin (provided that the alarm is enabled). When the INTCN bit is set to
logic 0, a square wave is output on the SQW/
INTB pin. This bit is set to logic 0 when power is first applied.
