7.4.5.2 LED Pattern Registers

Pattern data0, Pattern data1, Pattern data2, Pattern data3

Addr: 19h,1Ah,1Bh,1Ch

This registers contains the pattern data for the RGB current sinks.

Description

7:0

pattern_data0[7:0]

R/W

Pattern data0; if this register is changed and patern_color=1

no current source must have currX_mode = ‘LED pattern

controlled’ (11)

7:0

pattern_data1[15:8]

R/W

Pattern data1; if this register is changed and patern_color=1

no current source must have currX_mode = ‘LED pattern

controlled’ (11)

7:0

pattern_data2[23:16]

R/W

Pattern data2; if this register is changed and patern_color=1

no current source must have currX_mode = ‘LED pattern

controlled’ (11)

7:0

pattern_data3[31:24]

R/W

Pattern data3; if this register is changed and patern_color=1

no current source must have currX_mode = ‘LED pattern

controlled’ (11)

Note:

Update any of the pattern register only if none of the current sources is connected to the pattern

generator (‘xxxx’_mode must not be 11b). The pattern generator is automatically started at the

same time when any of the current sources is connected to the pattern generator

Pattern control

Addr: 18h

This register controls the LED pattern

Bit

Bit Name

Default

Access

Description

pattern_color

R/W

Defines the pattern type for the current sinks

0b = single 32 bit pattern (also set currX_mode = ‘LED

pattern controlled (11))

1b = RGB pattern with each 10 bits (also set

currX_mode = ‘LED pattern controlled (11))

2:1

pattern_delay

R/W

Delay between pattern

00b = 0 sec

01b = 1 sec (8 sec if pattern_slow=1)

10b = 2 sec (16 sec if pattern_slow=1)

11b = 3 sec (24 sec if pattern_slow=1)

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’; do not use for CURR1 or CURR2; do not

set CURR3x_mode to ‘other’ if softdim_pattern=1

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
