* If the high level causes inactive state (LED turns off), an external pull-up resister is required.

Width of Reset Signal
In an actual operating environment, the following considerations are needed for the width of the reset
signal that is applied to the nRESET pin:
Oscillator Startup Time at Power-up (Tstart)
The oscillator startup time (Tstart) is required for the crystal oscillator to stabilize. The startup time is
required for TMC2084 regardless of whether a crystal oscillator or an external clock is used. After the
oscillator startup time, the input clock to X1 pin becomes normal (after approximately 20 ms).
The reset signal must stay low longer than 6(Tx) is required after Tstart.
