If you want to generate only the Long Button, the Short Button must not be generated
immediately by pressing the steering wheel control button.
Put 1~254 in S-Hold Time.
The short button is generated when the button is released before Critical Time while S-Hold Time.
The long button is generated when the button is released after Critical Time while L-Hold Time.
Hold Time value 1 is about 10ms, so Hold Time value 254 is about 2540ms(2.54s).

Hold Time 0 means that the button keeps being pressed while you keep pressing the remote control button.
This is useful when you need to keep a key pressed in volume control.
(C, D channel support only Short Button and S-Hold Time.)
