Medium flash mode
To select this operating mode the Enable pins have to be connected as follows:
EN1=1, EN2=0, EN3=0
In medium flash mode the current is set between the Torch and the flash mode levels and can be adjusted
by connecting a resistor between the RMFL pin and the ground:
The medium flash current is then programmed using the following equation:
