Description
Force 32-kHz oscillator enable on.
This bit is used to allow software to force the SA-1110 to use the 32-kHz oscillator for
internal clocking functions instead of waiting for it to stabilize in the normal way. This
function is useful primarily to attain rapid functionality after a "warm" hardware reset when it
is known that the oscillator is stable. Use of this bit is intended for test purposes and some
customer use in special situations. It should be used with care, however, since setting this
bit when the 32-kHz oscillator is not stable will yield unpredictable results.
