Bits 7 to 4: Periodic Rate Select (PRS3–PRS0).
When
the oscillator is enabled (ENOSC = 1) the PF flag is set
at the rates determined by the following
table:
Bits 3 to 0: Square-Wave Rate Select (SRS3–SRS0).
When the oscillator is enabled (ENOSC = 1) and run-
ning, and the square-wave pin is enabled (SQWE = 1),
the SQW pin outputs a square-wave signal determined
by the SRS bits according to the following table:
