Selects internal oscillator between 32KHz and 32.768KHz to
supply the reference clock.
Selects between the internal oscillator and external oscillator
to supply the reference clock
Enabling Respiration causes the output of the mux to equal
the PLL frequency divided by the F Divider. If disabled, the
output of the mux is simply the PLL frequency. This
functionality allows lower drive and sampling frequencies to
be generated, as measuring respiration does not require high
frequencies.
