Fully Programmable Serializer/Deserializer

with UART/I

C Control Channel

ADDRESS BITS DEFAULT NAME DESCRIPTION

Control channel end timeout: (ETO) times out if ECU does not use control channel for this amount of time after it has

already used at least once.

7:4 1010 ETODIV

Control channel end timeout divider

Pixel clock is first divided by:

0000 = 16 1000 = 256

0001 = 16 1001 = 512

0010 = 16 1010 = 1024 (default)

0011 = 16 1011 = 2048

0100 = 16 1100 = 4096

0101 = 32 1101 = 8192

0110 = 64 1110 = 16,384

0111 = 128 1111 = 32,768

3:0 0000 ETOCNT

Control channel end timeout counter

Divided pixel clock is used to count up to (ETOCNT + 1)

7 0 VEDGE

VSYNC active edge at camera interface

0 = falling (default), 1 = rising

6 0 Reserved (set to 0)

5 1 CKEDGE

PCLK active edge at camera interface

0 = falling, 1 = rising (default)

40 PD

Power mode

0 = power-up, 1 = power-down

(when REM = 1 default is 1)

3 1 SEREN

Serialization enable

0 = disabled, 1 = enabled

(when REM = 1 default is 0)

2 0 BYPFPLL

Bypass filter PLL

0 = active (default), 1 = bypass

1 0 Reserved (set to 0)

0 0 PRBSEN

PRBS test enable

0 = disabled (default), 1 = enabled

7:1 1111101 DEVICEID 7-bit address of MAX9257

0 0 Reserved (set to 0)

7:1 1111111 EF End frame to close control channel

0 1 Reserved (set to 1)

7:1 1111100 DESID 7-bit address ID of MAX9258

0 0 Reserved (set to 0)
