RSTN should be set LOW at power-ON and after
reacquiring synchronization. Note that if RSTN is
LOW for longer than 1 µs, a through-current flows in
the internal dynamic circuits because the internal
clock is stopped. The through-current has no rated
value, so the reset pulse should be kept as short as
possible at all times other than at power-ON.
