Select the Charge Pump Mode of Operation:
0 ³ charge pump de−activated during a flash pulse
1 ³ charge pump activated during a flash pulse
Select the Flash mode
Control a flash sequence from the I2C port:
0 ³ the I2C trigger is de−activated, clear previous sequence
1 ³ the I2C trigger is activated and the flash pulse is forced on the positive
going pulse
Control the charge pump:
0 ³ charge pump de−activated
1 ³ charge pump activated
Control the pre charge mode:
0 ³ pre charge pump de−activated
1 ³ pre charge pump activated
