0XC9 – MPP PIN OUTPUT MODE CONTROL

Bit

Function

R/W

Description

Reset

GPP_VAL4

R/W

Select the general purpose value through the MPP4 pin for Ch4.

0 : “0” vaule, 1: “1” value

6-4

MPP_MODE4

R/W

Select the output mode for MPP4 pin.

Followings show the status when POLMPP4 register is set to 0. If

POLMPP4 register is set to 1, following values have inversed status.

0:Horizontal sync output.Low is H-sync active.

1:Vertical sync output.Low is V-sync active.

2:Field flag output.Low is field1(Odd),High is field2(Even).

3:Horizontal active signal output.High is H-active.

4:Vertical active & horizontal active signal output.High is VH-active.

5:No video flag.High is No-video,Low is Video.

6:Digital serial audio mixing data same as ADATM pin

7:GPP_VAL.Same as GPP_VAL4 register value.

If VDLOSSOE register is set to “1”, vdloss4 signal is output to MPP4

pin and these MPP_MODE4 function is not effective.

GPP_VAL3

R/W

Select the general purpose value through the MPP3 pin for Ch3.

0 : “0” vaule, 1: “1” value

2-0

MPP_MODE3

R/W

Select the output mode for MPP3 pin.

Followings show the status when POLMPP3 register is set to 0. If

each POLMPP3 register is set to 1, following values have inversed

status.

0:Horizontal sync output.Low is H-sync active.

1:Vertical sync output.Low is V-sync active.

2:Field flag output.Low is field1(Odd),High is field2(Even).

3:Horizontal active signal output.High is H-active.

4:Vertical active & horizontal active signal output.High is VH-active.

5:No video flag.High is No-video,Low is Video.

6:Digital serial audio mixing data same as ADATM pin

7:GPP_VAL.Same as GPP_VAL3 register value.

If VDLOSSOE register is set to “1”, vdloss3 signal is output to MPP3

pin and these MPP_MODE3 function is not effective.
