During recording, outputs

chroma signal after Y/C

separation or for chroma

signal input from Pin 53.

During playback, the playback

chroma signal is output.

During ACK, the output DC

becomes 0V.

Inputs chroma signal to Y/C

MIX circuit in the I/O block.

During component signal

recording or playback, this

signal is Y/C mixed and is

then output from V OUT.
