FRP input. This pulse is

used to invert the polarity of

the RGB output. Output is

inverted when Low, and non-

inverted when High.

Input level: High ≥ 4V

Low ≤ 1V

Note) ∗ in the Pin voltage indicates external applied voltage.

FRP pulse input for SID

output. This pulse is used to

invert the polarity of the SID

output. Output is inverted

when Low, and non-inverted

when High.

Input level: High ≥ 4V

Low ≤ 1V
