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

curr32_pattern

R/W

Additional CURR33 LED pattern control bit

0b = CURR32 controlled according curr32_mode register

1b = CURR32 controlled by LED pattern generator

curr33_pattern

R/W

Additional CURR33 LED pattern control bit

0b = CURR33 controlled according curr33_mode register

1b = CURR33 controlled by LED pattern generator

7.4.3 RGB Current Sinks RGB1, RGB2, RGB3 (VANA2,cpext)

The RGB1,RGB2, RGB3 are pins with different functionality. These pins can act as current sinks or as external

chargepump. In addition RGB3 can be programmed as Analog LDO supplied by VBAT3
