You need to guarantee that the rest of your circuit is in a safe and quiescent state while the micro is starting up. This is harder than it looks, when you consider that a reset or fast power-cycle may leave the rest of your circuit in an indeterminate state, or leave it powered up and running without the micro keeping an eye on it. | |

In some cases, such currents don't matter; in others they're an absolute killer. | |
