ABLC™ Configuration (0x40)

ABLC™ disable

0: ABLC™ enabled (default)

1: ABLC™ disabled

Reserved

Set to 0.

3:2

ABLC™ pixel width

Number of black pixels averaged every line for ABLC™

function

00: 16 pixels [default]

01: 32 pixels

10: 64 pixels

11: 128 pixels

6:4

ABLC™ bandwidth

ABLC™ Time constant (lines) = 2(5+[6:4])

000 = 32 lines

100 = 512 lines (default)

111 = 4096 lines

Reserved

Set to 0.

0x18

Output Format (0x00)

Bus Width

0: 24 bits: Data output on RP, GP, BP only; RS, GS, BS are all

driven low (default)

1: 48 bits: Data output on RP, GP, BP, RS, GS, BS

Interleaving

(48 bit mode only)

0: No interleaving: data changes on same edge of DATACLK

(default)

1: Interleaved: Secondary databus data changes on

opposite edge of DATACLK from primary databus

2Bus Swap

(48 bit mode only)

0: First data byte after trailing edge of HSOUT appears on

RP, GP, BP (default)

1: First data byte after trailing edge of HSOUT appears on

RS, GS, BS (primary and secondary busses are reversed)

Reserved

Set to 0.

422

(24 bit mode only)

0: Data is formatted as 4:4:4 (RGB, default)

1: Data is decimated to 4:2:2 (YUV), blue channel is driven

low

5DATACLK

Polarity

0: HSOUT, VSOUT, and Pixel Data change on falling edge of

DATACLK (default)

1: HSOUT, VSOUT, and Pixel Data change on rising edge of

DATACLK

VSOUT Polarity

0: Active High (default)

1: Active Low

HSOUT Polarity

0: Active High (default)

1: Active Low

HSOUT Width (0x10)

7:0

HSOUT Width

HSOUT width, in pixels. Minimum value is 0x01 for 24 bit

modes, 0x02 for 48 bit modes.

0x1A

Output Signal Disable (0x00)

Three-state RP[7:0]

0 = Output byte enabled

1 = Output byte three-stated
