bit3
TST
Test signal. Be sure to set to Low.
bit2
XJGLK
Normally set to Low. When Low, the decoding result is held during the
VCR variable-speed playback for home use. When High, it is not held.
Normally set to Low. When Low, the ID signal can be detected not only for
bit1
LNJ1
the line where it should locate but for one line before and after it. When High,
decoding is performed only to the line where the ID signal should locate.
bit0 LSB RES
Normally set to Low. When High, the decoding function is reset. Reset
immediately after switching the input signal such as for TV channels.
bit7 MSB ID5
ID decoding result 5th bit.
bit6
ID4
ID decoding result 4th bit.
bit5
ID3
ID decoding result 3rd bit.
bit4
ID1
ID decoding result 1st bit.
bit3
ID2
ID decoding result 2nd bit.
bit2
VBVLD High when the valid ID signal is detected.
bit1
IOLBX
Input value when OLBX is used as the general-purpose input port.
Input value when O169 is used as the general-purpose input port.
bit0 LSB IO169
ID decoding result 14th bit when O169 is used as the general-purpose
RD
output port or as the direct output.
bit7 MSB ID13
ID decoding result 13th bit.
bit6
ID12
ID decoding result 12th bit.
bit5
ID11
ID decoding result 11th bit.
bit4
ID10
ID decoding result 10th bit.
bit3
ID9
ID decoding result 9th bit.
bit2
ID8
ID decoding result 8th bit.
bit1
ID7
ID decoding result 7th bit.
bit0 LSB ID6
ID decoding result 6th bit.
