Symbol
Output value when the OLBX pin used as the general-purpose output port.
Output value when the O169 pin used as the general-purpose output port.
Settings whether the OLBX and O169 pins are used as the direct output
pin of decoding result or as the general-purpose I/O port.
Test signal. Be sure to set to Low.
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
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.
Normally set to Low. When High, the decoding function is reset. Reset
immediately after switching the input signal such as for TV channels.
ID decoding result 5th bit.
ID decoding result 4th bit.
ID decoding result 3rd bit.
ID decoding result 1st bit.
ID decoding result 2nd bit.
High when the valid ID signal is detected.
Input value when OLBX is used as the general-purpose input port.
Input value when O169 is used as the general-purpose input port.
ID decoding result 14th bit when O169 is used as the general-purpose
output port or as the direct output.
ID decoding result 13th bit.
ID decoding result 12th bit.
ID decoding result 11th bit.
ID decoding result 10th bit.
ID decoding result 9th bit.
ID decoding result 8th bit.
ID decoding result 7th bit.
ID decoding result 6th bit.
