Strobe_mode

01b

R/W

00 = Strobe mode 1 is selected. The strobe time is defined by

the value in register Strobe_mode1 (page 25) the maximum

strobe time is limited to 800ms.

01 = Strobe mode 2 is selected. The strobe time is defined by

the pulse length of the STROBE_SIGNAL and in addition it is

affected by the setting of register Strobe_mode2 (page 26).

1x = Strobe mode 3 is selected. The strobe time is defined by

the pulse length of STROBE_SIGNAL. The maximum strobe time

is unlimited.

preview_on

0R/W

0 = Current of current sinks is 0mA.

1 = Current of current sinks is defined by register

current1_preview

. If preview is controlled via pin GPIO0/P0

(see bit preview_ctrl), this bit has no effect.

preview_ctrl

0R/W

0 = Preview mode is controlled by bit preview_on (page 25).

1 = Preview mode is controlled by pin GPIO0/P0.

strobe_on

0R/W

0 = Current of current sinks is 0mA.

1 = Current of current sinks is defined by register

Current1_strobe

(page 20). If preview mode is controlled via

pin STROBE/F2 (see bit xstrobe_ctrl), this bit has no effect

xstrobe_ctrl

0R/W

0 = Strobe mode is controlled by pin STROBE/F2.

1 = Strobe mode is controlled by bit strobe_on (page 25).

Addr: 04

Strobe_mode1

This register sets the strobe time in mode 1.
