ENABLE/DISABLE vs. POWER DOWN
P - Power Down: When Pad 1 is LOW the oscillator stops running
T - Enable/Disable: When Pad 1 is LOW the internal oscillator
continues to run but the output (Pad 3) is in a
high impedance (Z) state.
Power Down:
Enable/Disable:
Disabled current consumption low,
recovery delayed.
Disabled current consumption lower than normal,
Recovery immediate.
