SQWE
OUT (output control): This bit presets the output logic level of the pin SQW/OUT, when the
output of the rectangular signal is locked.
SQWE (rectangular signal enabling): This bit, pre-set to the logic “1”, activates the generator
output. Frequency of the output rectangular signal is determined by the bits RS0 and RS1.
RS (frequency selection): These bits determine the frequency of the output rectangular signal,
when the output of the rectangular signal is activated. The table indicates the frequencies, which
can be selected by the bits RS.
