Slow Oscillator
Mode Enable
Slow Oscillator Mode is used to disconnect the
input reference crystal/clock on the XI pin and
select the on-chip slow oscillator when the
KSZ8051 device is not in use after power-up.
1 = Enable
0 = Disable
This bit automatically sets software power down
to the analog side when enabled.
