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
