Description

STATUS[2]

Status signal output

Selected by internal register OMR[1]

OMR[1]: 0

OMR[1]: 1

STATUS[1]

VBI interval multiplex signal detection output

0: non-detection, 1: detection

M[7]

Field memory control signal; RE output

M[6]

Field memory control signal; WE output

M[5]

Field memory control signal; RSTR output

M[4]

Field memory control signal; RSTW output

M[3]

Test output pin, normally "L" output

M[2]

I2C-bus slave address select

0: 1000001X

1: 1000011X (no internal pull-up or pull-down resistor)

M[1]

Pin for setting by either external pin or internal register in order to select

analog unit gain value (MGC) and video signal input pin.

(no internal pull-up or pull-down resistor)

0: external pin mode

Gain value setting: pins 94 to 96 (GAINS[2:0]) are used

Input pin setting: pins 97 to 99 (INS[2:0]) are used

1: register mode

Gain value setting: register ADC2[6:4]

Input pin setting: register ADC1[2:0]

Internal register setting is invalid when external pin mode is set.

M[0]

Selection of external field memory control signal output

If field memory is not used, set M[0] to 0.

0: M[7:4] outputs are invalid

1: M[7:4] outputs are valid

HLOCK sync detection output

0: non-detection, 1: detection

STATUS[3]

Status signal output

Selected by internal register OMR[0]

OMR[0]: 0

OMR[0]: 1
