Function

Typical

Operation

Value

Bit No.

(LSB = 0)

Label

Sub-

Address

(decimal)

I2C registers for OUTPUT CONTROL

HALFOUT

Output drive duration

0 = output active a full clock cycle (only one IC on Picture Bus)

1 = output active half a clock cycle (more than one IC on Picture Bus)

AVODIS

disable AVO pin

0 = AVO pin is active

1 = AVO pin is tristate

PUDIS

disable pull-up transistors at GL, RC, and B output pins

0 = pull-up on (output is in push-pull mode)

1 = pull-up off (output is in open drain mode)

LOAD

2–0

adjust load of AVO, GL, RC, B and PRIO

(select lowest possible load to keep electromagnetic radiation

and noise at A/D-Converter low)

LOAD |

GL, RC, B, and AVO outputs

@PVDD = 5 Volt

@PVDD = 3.3 Volt

NOTE:

Total CLOAD at pins GL, RC, B, AVO, and PRIO must not exceed 2 nF.

CLoad = max. load capacitance for AVO

CLoad = max. load capacitance for GL, RC, and B at push-pull mode

12C:<14> PUDIS = 0

ILoad = max. sink current for GL, RC, and B at open drain mode

12C:<14> PUDIS = 1
