Bit 7: Output Control (OUT). This bit controls the output level of the SQW/OUT pin when the square-
wave output is disabled. If SQWE = 0, the logic level on the SQW/OUT pin is 1 if OUT = 1 and is 0 if
OUT = 0.
Bit 4: Square-Wave Enable (SQWE). This bit, when set to logic 1, enables the oscillator output. The
frequency of the square-wave output depends upon the value of the RS0 and RS1 bits. With the square-
wave output set to 1Hz, the clock registers update on the falling edge of the square wave.
Bits 1, 0: Rate Select (RS1, RS0). These bits control the frequency of the square-wave output when the
square-wave output has been enabled. The following table lists the square-wave frequencies that can be
selected with the RS bits.
