Table 10.
1. In parallel interface mode the assist and torch current is set to 80mA for a single LED and 40mA for a dual LED
2. In parallel interface mode the flash current is set to 500mA for one LED and 320mA (each LED) for two LEDs
3. For a dual flash LED leave boost_current=0 (max 500mA for each LED - combined current of 1000mA)
