29 - 70

Addr: 10h

Curr3x other

This register selects the current of the current sinks30..33

Bit

Bit Name

Default

Access Description

5:0

curr3x_other

R/W

Selects curr3x current, if curr30, curr31, curr32 or curr33 are not

used for strobe/preview (CurX_mode=11b)

00h = 0 mA

01h = 0.6mA

...

3Fh = 37.8mA

Addr: 03h

curr3 control

This register select the mode of the current sinks30 - 33

Bit

Bit Name

Default

Description

1:0

curr30_mode

R/W

Select the mode of the current sink curr30

00b = off

01b = strobe/preview

10b = curr3x_other PWM controlled

11b = curr3x_other

3:2

curr31_mode

R/W

Select the mode of the current sink curr31

00b = off

01b = strobe/preview

10b = curr3x_other PWM controlled

11b = curr3x_other

5:4

curr32_mode

R/W

Select the mode of the current sink curr32

00b = off

01b = strobe/preview

10b = curr3x_other PWM controlled

11b = curr3x_other

7:6

curr33_mode

R/W

Select the mode of the current sink curr33

00b = off

01b = strobe/preview

10b = curr3x_other PWM controlled

11b = curr3x_other

Addr: 18h

Pattern control

This register controls the RGB pattern

Bit

Bit Name

Default

Access

Description

pattern_color

R/W

Defines the pattern type for the RGBx current sinks

0b = single 32 bit pattern (also set rgbx_mode = 11)

1b = RGB pattern with each 10 bits (set all rgbx_mode = 11)

2:1

pattern_delay

R/W

Delay between pattern

00b = 0 sec

01b = 1 sec

10b = 2 sec

11b = 3 sec

softdim_pattern

R/W

Enable the ‘soft’ dimming feature for the pattern generator

0 = Pattern generator directly control current sources

1 = ‘Soft Dimming’ is performed – see section ’Soft Dimming

for pattern’

curr30_pattern

R/W

Additional CURR33 LED pattern control bit

0b = CURR30 controlled according curr30_mode register

1b = CURR30 controlled by LED pattern generator

curr31_pattern

R/W

Additional CURR33 LED pattern control bit

0b = CURR31 controlled according curr31_mode register

1b = CURR31 controlled by LED pattern generator
